See The Sentence for definitions of sentence, clause, and dependent clause.
A sentence which contains just one clause is called a simple sentence.
A sentence which contains one independent clause and one or more dependent clauses is called a complex sentence. (Dependent clauses are also called subordinate clauses.)
There are three basic types of dependent clauses: adjective clauses, adverb clauses, and noun clauses. (Adjective clauses are also called relative clauses.)
This page contains information about noun clauses. Also see Adjective Clauses and Adverb Clauses.
________________________________________
A. Noun clauses perform the same functions in sentences that nouns do:
A noun clause can be a subject of a verb:
What Billy did shocked his friends.
A noun clause can be an object of a verb:
Billy’s friends didn’t know that he couldn’t swim.
A noun clause can be a subject complement:
Billy’s mistake was that he refused to take lessons.
A noun clause can be an object of a preposition:
Mary is not responsible for what Billy did.
A noun clause (but not a noun) can be an adjective complement:
Everybody is sad that Billy drowned.
________________________________________
B. You can combine two independent clauses by changing one to a noun clause and using it in one of the ways listed above. The choice of the noun clause marker (see below) depends on the type of clause you are changing to a noun clause:
To change a statement to a noun clause use that:
I know + Billy made a mistake =
I know that Billy made a mistake.
To change a yes/no question to a noun clause, use if or whether:
George wonders + Does Fred know how to cook? =
George wonders if Fred knows how to cook.
To change a wh-question to a noun clause, use the wh-word:
I don’t know + Where is George? =
I don’t know where George is.
C. The subordinators in noun clauses are called noun clause markers. Here is a list of the noun clause markers:
that
if, whether
Wh-words: how, what, when, where, which, who, whom, whose, why
Wh-ever words: however, whatever, whenever, wherever, whichever, whoever, whomever
________________________________________
D. Except for that, noun clause markers cannot be omitted. Only that can be omitted, but it can be omitted only if it is not the first word in a sentence:
correct:
Billy’s friends didn’t know that he couldn’t swim.
correct:
Billy’s friends didn’t know he couldn’t swim.
correct:
Billy’s mistake was that he refused to take lessons.
correct:
Billy’s mistake was he refused to take lessons.
correct:
That Billy jumped off the pier surprised everyone.
not correct:
* Billy jumped off the pier surprised everyone.
E. Statement word order is always used in a noun clause, even if the main clause is a question:
not correct:
* Do you know what time is it? (Question word order: is it)
correct:
Do you know what time it is? (Statement word order: it is)
not correct:
* Everybody wondered where did Billy go. (Question word order: did Billy go)
correct:
Everybody wondered where Billy went. (Statement word order: Billy went)
F. Sequence of tenses in sentences containing noun clauses:
When the main verb (the verb in the independent clause) is present, the verb in the noun clause is:
future if its action/state is later
He thinks that the exam next week will be hard.
He thinks that the exam next week is going to be hard.
present if its action/state is at the same time
He thinks that Mary is taking the exam right now.
past if its action/state is earlier
He thinks that George took the exam yesterday.
When the main verb (the verb in the independent clause) is past, the verb in the noun clause is:
was/were going to or would + BASE if its action/state is later
He thought that the exam the following week was going to be hard.
He thought that the exam the following week would be hard.
past if its action/state is at the same time
He thought that Mary was taking the exam then.
past perfect if its action/state is earlier
He thought that George had taken the exam the day before.
If the action/state of the noun clause is still in the future (that is, after the writer has written the sentence), then a future verb can be used even if the main verb is past.
The astronaut said that people will live on other planets someday.
If the action/state of the noun clause continues in the present (that is, at the time the writer is writing the sentence) or if the noun clause expresses a general truth or fact, the simple present tense can be used even if the main verb is past.
We learned that English is not easy.
The boys knew that the sun rises in the east.
G. Here are some examples of sentences which contain one noun clause (underlined) and one independent clause:
Noun clauses as subjects of verbs:
That George learned how to swim is a miracle.
Whether Fred can get a better job is not certain.
What Mary said confused her parents.
However you learn to spell is OK with me.
Noun clauses as objects of verbs:
We didn’t know that Billy would jump.
We didn’t know Billy would jump.
Can you tell me if Fred is here?
I don’t know where he is.
George eats whatever is on his plate.
Noun clauses as subject complements:
The truth is that Billy was not very smart.
The truth is Billy was not very smart.
The question is whether other boys will try the same thing.
The winner will be whoever runs fastest.
Noun clauses as objects of prepositions:
Billy didn’t listen to what Mary said.
He wants to learn about whatever is interesting.
Noun clauses as adjective complements:
He is happy that he is learning English.
We are all afraid that the final exam will be difficult.

CONJUNCTIONS

Conjunctions

Definition
Some words are satisfied spending an evening at home, alone, eating ice-cream right out of the box, watching Seinfeld re-runs on TV, or reading a good book. Others aren’t happy unless they’re out on the town, mixing it up with other words; they’re joiners and they just can’t help themselves. A conjunction is a joiner, a word that connects (conjoins) parts of a sentence.
Coordinating Conjunctions
The simple, little conjunctions are called coordinating conjunctions (you can click on the words to see specific descriptions of each one):
Coordinating Conjunctions
and
but
or
yet
for
nor
so

(It may help you remember these conjunctions by recalling that they all have fewer than four letters. Also, remember the acronym FANBOYS: For-And-Nor-But-Or-Yet-So. Be careful of the words then and now; neither is a coordinating conjunction, so what we say about coordinating conjunctions’ roles in a sentence and punctuation does not apply to those two words.)
When a coordinating conjunction connects two independent clauses, it is often (but not always) accompanied by a comma:
• Ulysses wants to play for UConn, but he has had trouble meeting the academic requirements.
When the two independent clauses connected by a coordinating conjunction are nicely balanced or brief, many writers will omit the comma:
• Ulysses has a great jump shot but he isn’t quick on his feet.
The comma is always correct when used to separate two independent clauses connected by a coordinating conjunction. See Punctuation Between Two Independent Clauses for further help.
A comma is also correct when and is used to attach the last item of a serial list, although many writers (especially in newspapers) will omit that final comma:
• Ulysses spent his summer studying basic math, writing, and reading comprehension.
When a coordinating conjunction is used to connect all the elements in a series, a comma is not used:
• Presbyterians and Methodists and Baptists are the prevalent Protestant congregations in Oklahoma.
A comma is also used with but when expressing a contrast:
• This is a useful rule, but difficult to remember.
In most of their other roles as joiners (other than joining independent clauses, that is), coordinating conjunctions can join two sentence elements without the help of a comma.
• Hemingway and Fitzgerald are among the American expatriates of the between-the-wars era.
• Hemingway was renowned for his clear style and his insights into American notions of male identity.
• It is hard to say whether Hemingway or Fitzgerald is the more interesting cultural icon of his day.
• Although Hemingway is sometimes disparaged for his unpleasant portrayal of women and for his glorification of machismo, we nonetheless find some sympathetic, even heroic, female figures in his novels and short stories.
Beginning a Sentence with And or But
A frequently asked question about conjunctions is whether and or but can be used at the beginning of a sentence. This is what R.W. Burchfield has to say about this use of and:
There is a persistent belief that it is improper to begin a sentence with And, but this prohibition has been cheerfully ignored by standard authors from Anglo-Saxon times onwards. An initial And is a useful aid to writers as the narrative continues.
from The New Fowler’s Modern English Usage
edited by R.W. Burchfield. Clarendon Press: Oxford, England. 1996.
Used with the permission of Oxford University Press.
The same is true with the conjunction but. A sentence beginning with and or but will tend to draw attention to itself and its transitional function. Writers should examine such sentences with two questions in mind: (1) would the sentence and paragraph function just as well without the initial conjunction? (2) should the sentence in question be connected to the previous sentence? If the initial conjunction still seems appropriate, use it.
Among the coordinating conjunctions, the most common, of course, are and, but, and or. It might be helpful to explore the uses of these three little words. The examples below by no means exhaust the possible meanings of these conjunctions.
AND
a. To suggest that one idea is chronologically sequential to another: “Tashonda sent in her applications and waited by the phone for a response.”
b. To suggest that one idea is the result of another: “Willie heard the weather report and promptly boarded up his house.”
c. To suggest that one idea is in contrast to another (frequently replaced by but in this usage): “Juanita is brilliant and Shalimar has a pleasant personality.
d. To suggest an element of surprise (sometimes replaced by yet in this usage): “Hartford is a rich city and suffers from many symptoms of urban blight.”
e. To suggest that one clause is dependent upon another, conditionally (usually the first clause is an imperative): “Use your credit cards frequently and you’ll soon find yourself deep in debt.”
f. To suggest a kind of “comment” on the first clause: “Charlie became addicted to gambling — and that surprised no one who knew him.”

BUT
a. To suggest a contrast that is unexpected in light of the first clause: “Joey lost a fortune in the stock market, but he still seems able to live quite comfortably.”
b. To suggest in an affirmative sense what the first part of the sentence implied in a negative way (sometimes replaced by on the contrary): “The club never invested foolishly, but used the services of a sage investment counselor.”
c. To connect two ideas with the meaning of “with the exception of” (and then the second word takes over as subject): “Everybody but Goldenbreath is trying out for the team.”
OR
a. To suggest that only one possibility can be realized, excluding one or the other: “You can study hard for this exam or you can fail.”
b. To suggest the inclusive combination of alternatives: “We can broil chicken on the grill tonight, or we can just eat leftovers.
c. To suggest a refinement of the first clause: “Smith College is the premier all-women’s college in the country, or so it seems to most Smith College alumnae.”
d. To suggest a restatement or “correction” of the first part of the sentence: “There are no rattlesnakes in this canyon, or so our guide tells us.”
e. To suggest a negative condition: “The New Hampshire state motto is the rather grim “Live free or die.”
f. To suggest a negative alternative without the use of an imperative (see use of and above): “They must approve his political style or they wouldn’t keep electing him mayor.”

The Others . . .
The conjunction NOR is not extinct, but it is not used nearly as often as the other conjunctions, so it might feel a bit odd when nor does come up in conversation or writing. Its most common use is as the little brother in the correlative pair, neither-nor (see below):
• He is neither sane nor brilliant.
• That is neither what I said nor what I meant.
>It can be used with other negative expressions:
• That is not what I meant to say, nor should you interpret my statement as an admission of guilt.
It is possible to use nor without a preceding negative element, but it is unusual and, to an extent, rather stuffy:
• George’s handshake is as good as any written contract, nor has he ever proven untrustworthy.
The word YET functions sometimes as an adverb and has several meanings: in addition (“yet another cause of trouble” or “a simple yet noble woman”), even (“yet more expensive”), still (“he is yet a novice”), eventually (“they may yet win”), and so soon as now (“he’s not here yet”). It also functions as a coordinating conjunction meaning something like “nevertheless” or “but.” The word yet seems to carry an element of distinctiveness that but can seldom register.
• John plays basketball well, yet his favorite sport is badminton.
• The visitors complained loudly about the heat, yet they continued to play golf every day.
In sentences such as the second one, above, the pronoun subject of the second clause (“they,” in this case) is often left out. When that happens, the comma preceding the conjunction might also disappear: “The visitors complained loudly yet continued to play golf every day.”
Yet is sometimes combined with other conjunctions, but or and. It would not be unusual to see and yet in sentences like the ones above. This usage is acceptable.
The word FOR is most often used as a preposition, of course, but it does serve, on rare occasions, as a coordinating conjunction. Some people regard the conjunction for as rather highfalutin and literary, and it does tend to add a bit of weightiness to the text. Beginning a sentence with the conjunction “for” is probably not a good idea, except when you’re singing “For he’s a jolly good fellow. “For” has serious sequential implications and in its use the order of thoughts is more important than it is, say, with because or since. Its function is to introduce the reason for the preceding clause:
• John thought he had a good chance to get the job, for his father was on the company’s board of trustees.
• Most of the visitors were happy just sitting around in the shade, for it had been a long, dusty journey on the train.
Be careful of the conjunction SO. Sometimes it can connect two independent clauses along with a comma, but sometimes it can’t. For instance, in this sentence,
• Soto is not the only Olympic athlete in his family, so are his brother, sister, and his Uncle Chet.
where the word so means “as well” or “in addition,” most careful writers would use a semicolon between the two independent clauses. In the following sentence, where so is acting like a minor-league “therefore,” the conjunction and the comma are adequate to the task:
• Soto has always been nervous in large gatherings, so it is no surprise that he avoids crowds of his adoring fans.
Sometimes, at the beginning of a sentence, so will act as a kind of summing up device or transition, and when it does, it is often set off from the rest of the sentence with a comma:
• So, the sheriff peremptorily removed the child from the custody of his parents.
The Case of Then and Than
In some parts of the United States, we are told, then and than not only look alike, they sound alike. Like a teacher with twins in her classroom, you need to be able to distinguish between these two words; otherwise, they’ll become mischievous. They are often used and they should be used for the right purposes.

Than is used to make comparisons. In the sentence “Piggy would rather be rescued then stay on the island,” we have employed the wrong word because a comparison is being made between Piggy’s two choices; we need than instead. In the sentence, “Other than Pincher Martin, Golding did not write another popular novel,” the adverbial construction “other than” helps us make an implied comparison; this usage is perfectly acceptable in the United States but careful writers in the UK try to avoid it (Burchfield).
Generally, the only question about than arises when we have to decide whether the word is being used as a conjunction or as a preposition. If it’s a preposition (and Merriam-Webster’s dictionary provides for this usage), then the word that follows it should be in the object form.
• He’s taller and somewhat more handsome than me.
• Just because you look like him doesn’t mean you can play better than him.
Most careful writers, however, will insist that than be used as a conjunction; it’s as if part of the clause introduced by than has been left out:
• He’s taller and somewhat more handsome than I [am handsome].
• You can play better than he [can play].
In formal, academic text, you should probably use than as a conjunction and follow it with the subject form of a pronoun (where a pronoun is appropriate).
Then is a conjunction, but it is not one of the little conjunctions listed at the top of this page. We can use the FANBOYS conjunctions to connect two independent clauses; usually, they will be accompanied (preceded) by a comma. Too many students think that then works the same way: “Caesar invaded Gaul, then he turned his attention to England.” You can tell the difference between then and a coordinating conjunction by trying to move the word around in the sentence. We can write “he then turned his attention to England”; “he turned his attention, then, to England”; he turned his attention to England then.” The word can move around within the clause. Try that with a conjunction, and you will quickly see that the conjunction cannot move around. “Caesar invaded Gaul, and then he turned his attention to England.” The word and is stuck exactly there and cannot move like then, which is more like an adverbial conjunction (or conjunctive adverb — see below) than a coordinating conjunction. Our original sentence in this paragraph — “Caesar invaded Gaul, then he turned his attention to England” — is a comma splice, a faulty sentence construction in which a comma tries to hold together two independent clauses all by itself: the comma needs a coordinating conjunction to help out, and the word then simply doesn’t work that way.
Subordinating Conjunctions
A Subordinating Conjunction (sometimes called a dependent word or subordinator) comes at the beginning of a Subordinate (or Dependent) Clause and establishes the relationship between the dependent clause and the rest of the sentence. It also turns the clause into something that depends on the rest of the sentence for its meaning.
• He took to the stage as though he had been preparing for this moment all his life.
• Because he loved acting, he refused to give up his dream of being in the movies.
• Unless we act now, all is lost.
Notice that some of the subordinating conjunctions in the table below — after, before, since — are also prepositions, but as subordinators they are being used to introduce a clause and to subordinate the following clause to the independent element in the sentence.
Common Subordinating Conjunctions
after
although
as
as if
as long as

if only
in order that
now that
once
rather than
since
so that

The Case of Like and As
Strictly speaking, the word like is a preposition, not a conjunction. It can, therefore, be used to introduce a prepositional phrase (“My brother is tall like my father”), but it should not be used to introduce a clause (“My brother can’t play the piano like as he did before the accident” or “It looks like as if basketball is quickly overtaking baseball as America’s national sport.”). To introduce a clause, it’s a good idea to use as, as though, or as if, instead.
• Like As I told you earlier, the lecture has been postponed.
• It looks like as if it’s going to snow this afternoon.
• Johnson kept looking out the window like as though he had someone waiting for him.
In formal, academic text, it’s a good idea to reserve the use of like for situations in which similarities are being pointed out:
• This community college is like a two-year liberal arts college.
However, when you are listing things that have similarities, such as is probably more suitable:
• The college has several highly regarded neighbors, like such as the Mark Twain House, St. Francis Hospital, the Connecticut Historical Society, and the UConn Law School.

Omitting That
The word that is used as a conjunction to connect a subordinate clause to a preceding verb. In this construction that is sometimes called the “expletive that.” Indeed, the word is often omitted to good effect, but the very fact of easy omission causes some editors to take out the red pen and strike out the conjunction that wherever it appears. In the following sentences, we can happily omit the that (or keep it, depending on how the sentence sounds to us):
• Isabel knew [that] she was about to be fired.
• She definitely felt [that] her fellow employees hadn’t supported her.
• I hope [that] she doesn’t blame me.
Sometimes omitting the that creates a break in the flow of a sentence, a break that can be adequately bridged with the use of a comma:
• The problem is, that production in her department has dropped.
• Remember, that we didn’t have these problems before she started working here.
As a general rule, if the sentence feels just as good without the that, if no ambiguity results from its omission, if the sentence is more efficient or elegant without it, then we can safely omit the that. Theodore Bernstein lists three conditions in which we should maintain the conjunction that:
• When a time element intervenes between the verb and the clause: “The boss said yesterday that production in this department was down fifty percent.” (Notice the position of “yesterday.”)
• When the verb of the clause is long delayed: “Our annual report revealed that some losses sustained by this department in the third quarter of last year were worse than previously thought.” (Notice the distance between the subject “losses” and its verb, “were.”)
• When a second that can clear up who said or did what: “The CEO said that Isabel’s department was slacking off and that production dropped precipitously in the fourth quarter.” (Did the CEO say that production dropped or was the drop a result of what he said about Isabel’s department? The second that makes the sentence clear.)

Beginning a Sentence with Because
Somehow, the notion that one should not begin a sentence with the subordinating conjunction because retains a mysterious grip on people’s sense of writing proprieties. This might come about because a sentence that begins with because could well end up a fragment if one is not careful to follow up the “because clause” with an independent clause.
• Because e-mail now plays such a huge role in our communications industry.
When the “because clause” is properly subordinated to another idea (regardless of the position of the clause in the sentence), there is absolutely nothing wrong with it:
• Because e-mail now plays such a huge role in our communications industry, the postal service would very much like to see it taxed in some manner.
Correlative Conjunctions
Some conjunctions combine with other words to form what are called correlative conjunctions. They always travel in pairs, joining various sentence elements that should be treated as grammatically equal.
• She led the team not only in statistics but also by virtue of her enthusiasm.
• Polonius said, “Neither a borrower nor a lender be.”
• Whether you win this race or lose it doesn’t matter as long as you do your best.
Correlative conjunctions sometimes create problems in parallel form. Click for help with those problems. Here is a brief list of common correlative conjunctions.

both . . . and
not only . . . but also
not . . . but
either . . . or neither . . . nor
whether . . . or
as . . . as
Conjunctive Adverbs
The conjunctive adverbs such as however, moreover, nevertheless, consequently, as a result are used to create complex relationships between ideas. Refer to the section on Coherence: Transitions Between Ideas for an extensive list of conjunctive adverbs categorized according to their various uses and for some advice on their application within sentences (including punctuation issues).

Definition
Some words are satisfied spending an evening at home, alone, eating ice-cream right out of the box, watching Seinfeld re-runs on TV, or reading a good book. Others aren’t happy unless they’re out on the town, mixing it up with other words; they’re joiners and they just can’t help themselves. A conjunction is a joiner, a word that connects (conjoins) parts of a sentence.

b. To suggest that one idea is the result of another: “Willie heard the weather report and promptly boarded up his house.”
c. To suggest that one idea is in contrast to another (frequently replaced by but in this usage): “Juanita is brilliant and Shalimar has a pleasant personality.
d. To suggest an element of surprise (sometimes replaced by yet in this usage): “Hartford is a rich city and suffers from many symptoms of urban blight.”
e. To suggest that one clause is dependent upon another, conditionally (usually the first clause is an imperative): “Use your credit cards frequently and you’ll soon find yourself deep in debt.”

The Others . . .
The conjunction NOR is not extinct, but it is not used nearly as often as the other conjunctions, so it might feel a bit odd when nor does come up in conversation or writing. Its most common use is as the little brother in the correlative pair, neither-nor (see below):
• He is neither sane nor brilliant.
• That is neither what I said nor what I meant.
>It can be used with other negative expressions:
• That is not what I meant to say, nor should you interpret my statement as an admission of guilt.
It is possible to use nor without a preceding negative element, but it is unusual and, to an extent, rather stuffy:
• George’s handshake is as good as any written contract, nor has he ever proven untrustworthy.
The word YET functions sometimes as an adverb and has several meanings: in addition (“yet another cause of trouble” or “a simple yet noble woman”), even (“yet more expensive”), still (“he is yet a novice”), eventually (“they may yet win”), and so soon as now (“he’s not here yet”). It also functions as a coordinating conjunction meaning something like “nevertheless” or “but.” The word yet seems to carry an element of distinctiveness that but can seldom register.
• John plays basketball well, yet his favorite sport is badminton.
• The visitors complained loudly about the heat, yet they continued to play golf every day.
In sentences such as the second one, above, the pronoun subject of the second clause (“they,” in this case) is often left out. When that happens, the comma preceding the conjunction might also disappear: “The visitors complained loudly yet continued to play golf every day.”
Yet is sometimes combined with other conjunctions, but or and. It would not be unusual to see and yet in sentences like the ones above. This usage is acceptable.
The word FOR is most often used as a preposition, of course, but it does serve, on rare occasions, as a coordinating conjunction. Some people regard the conjunction for as rather highfalutin and literary, and it does tend to add a bit of weightiness to the text. Beginning a sentence with the conjunction “for” is probably not a good idea, except when you’re singing “For he’s a jolly good fellow. “For” has serious sequential implications and in its use the order of thoughts is more important than it is, say, with because or since. Its function is to introduce the reason for the preceding clause:
• John thought he had a good chance to get the job, for his father was on the company’s board of trustees.
• Most of the visitors were happy just sitting around in the shade, for it had been a long, dusty journey on the train.
Be careful of the conjunction SO. Sometimes it can connect two independent clauses along with a comma, but sometimes it can’t. For instance, in this sentence,
• Soto is not the only Olympic athlete in his family, so are his brother, sister, and his Uncle Chet.
where the word so means “as well” or “in addition,” most careful writers would use a semicolon between the two independent clauses. In the following sentence, where so is acting like a minor-league “therefore,” the conjunction and the comma are adequate to the task:
• Soto has always been nervous in large gatherings, so it is no surprise that he avoids crowds of his adoring fans.
Sometimes, at the beginning of a sentence, so will act as a kind of summing up device or transition, and when it does, it is often set off from the rest of the sentence with a comma:
• So, the sheriff peremptorily removed the child from the custody of his parents.
The Case of Then and Than
In some parts of the United States, we are told, then and than not only look alike, they sound alike. Like a teacher with twins in her classroom, you need to be able to distinguish between these two words; otherwise, they’ll become mischievous. They are often used and they should be used for the right purposes.

Than is used to make comparisons. In the sentence “Piggy would rather be rescued then stay on the island,” we have employed the wrong word because a comparison is being made between Piggy’s two choices; we need than instead. In the sentence, “Other than Pincher Martin, Golding did not write another popular novel,” the adverbial construction “other than” helps us make an implied comparison; this usage is perfectly acceptable in the United States but careful writers in the UK try to avoid it (Burchfield).
Generally, the only question about than arises when we have to decide whether the word is being used as a conjunction or as a preposition. If it’s a preposition (and Merriam-Webster’s dictionary provides for this usage), then the word that follows it should be in the object form.
• He’s taller and somewhat more handsome than me.
• Just because you look like him doesn’t mean you can play better than him.
Most careful writers, however, will insist that than be used as a conjunction; it’s as if part of the clause introduced by than has been left out:
• He’s taller and somewhat more handsome than I [am handsome].
• You can play better than he [can play].
In formal, academic text, you should probably use than as a conjunction and follow it with the subject form of a pronoun (where a pronoun is appropriate).
Then is a conjunction, but it is not one of the little conjunctions listed at the top of this page. We can use the FANBOYS conjunctions to connect two independent clauses; usually, they will be accompanied (preceded) by a comma. Too many students think that then works the same way: “Caesar invaded Gaul, then he turned his attention to England.” You can tell the difference between then and a coordinating conjunction by trying to move the word around in the sentence. We can write “he then turned his attention to England”; “he turned his attention, then, to England”; he turned his attention to England then.” The word can move around within the clause. Try that with a conjunction, and you will quickly see that the conjunction cannot move around. “Caesar invaded Gaul, and then he turned his attention to England.” The word and is stuck exactly there and cannot move like then, which is more like an adverbial conjunction (or conjunctive adverb — see below) than a coordinating conjunction. Our original sentence in this paragraph — “Caesar invaded Gaul, then he turned his attention to England” — is a comma splice, a faulty sentence construction in which a comma tries to hold together two independent clauses all by itself: the comma needs a coordinating conjunction to help out, and the word then simply doesn’t work that way.
Subordinating Conjunctions
A Subordinating Conjunction (sometimes called a dependent word or subordinator) comes at the beginning of a Subordinate (or Dependent) Clause and establishes the relationship between the dependent clause and the rest of the sentence. It also turns the clause into something that depends on the rest of the sentence for its meaning.
• He took to the stage as though he had been preparing for this moment all his life.
• Because he loved acting, he refused to give up his dream of being in the movies.
• Unless we act now, all is lost.
Notice that some of the subordinating conjunctions in the table below — after, before, since — are also prepositions, but as subordinators they are being used to introduce a clause and to subordinate the following clause to the independent element in the sentence.

The Case of Like and As
Strictly speaking, the word like is a preposition, not a conjunction. It can, therefore, be used to introduce a prepositional phrase (“My brother is tall like my father”), but it should not be used to introduce a clause (“My brother can’t play the piano like as he did before the accident” or “It looks like as if basketball is quickly overtaking baseball as America’s national sport.”). To introduce a clause, it’s a good idea to use as, as though, or as if, instead.
• Like As I told you earlier, the lecture has been postponed.
• It looks like as if it’s going to snow this afternoon.
• Johnson kept looking out the window like as though he had someone waiting for him.
In formal, academic text, it’s a good idea to reserve the use of like for situations in which similarities are being pointed out:
• This community college is like a two-year liberal arts college.
However, when you are listing things that have similarities, such as is probably more suitable:
• The college has several highly regarded neighbors, like such as the Mark Twain House, St. Francis Hospital, the Connecticut Historical Society, and the UConn Law School.

Omitting That
The word that is used as a conjunction to connect a subordinate clause to a preceding verb. In this construction that is sometimes called the “expletive that.” Indeed, the word is often omitted to good effect, but the very fact of easy omission causes some editors to take out the red pen and strike out the conjunction that wherever it appears. In the following sentences, we can happily omit the that (or keep it, depending on how the sentence sounds to us):
• Isabel knew [that] she was about to be fired.
• She definitely felt [that] her fellow employees hadn’t supported her.
• I hope [that] she doesn’t blame me.
Sometimes omitting the that creates a break in the flow of a sentence, a break that can be adequately bridged with the use of a comma:
• The problem is, that production in her department has dropped.
• Remember, that we didn’t have these problems before she started working here.
As a general rule, if the sentence feels just as good without the that, if no ambiguity results from its omission, if the sentence is more efficient or elegant without it, then we can safely omit the that. Theodore Bernstein lists three conditions in which we should maintain the conjunction that:
• When a time element intervenes between the verb and the clause: “The boss said yesterday that production in this department was down fifty percent.” (Notice the position of “yesterday.”)
• When the verb of the clause is long delayed: “Our annual report revealed that some losses sustained by this department in the third quarter of last year were worse than previously thought.” (Notice the distance between the subject “losses” and its verb, “were.”)
• When a second that can clear up who said or did what: “The CEO said that Isabel’s department was slacking off and that production dropped precipitously in the fourth quarter.” (Did the CEO say that production dropped or was the drop a result of what he said about Isabel’s department? The second that makes the sentence clear.)

Beginning a Sentence with Because
Somehow, the notion that one should not begin a sentence with the subordinating conjunction because retains a mysterious grip on people’s sense of writing proprieties. This might come about because a sentence that begins with because could well end up a fragment if one is not careful to follow up the “because clause” with an independent clause.
• Because e-mail now plays such a huge role in our communications industry.
When the “because clause” is properly subordinated to another idea (regardless of the position of the clause in the sentence), there is absolutely nothing wrong with it:
• Because e-mail now plays such a huge role in our communications industry, the postal service would very much like to see it taxed in some manner.
Correlative Conjunctions
Some conjunctions combine with other words to form what are called correlative conjunctions. They always travel in pairs, joining various sentence elements that should be treated as grammatically equal.
• She led the team not only in statistics but also by virtue of her enthusiasm.
• Polonius said, “Neither a borrower nor a lender be.”
• Whether you win this race or lose it doesn’t matter as long as you do your best.
Correlative conjunctions sometimes create problems in parallel form. Click for help with those problems. Here is a brief list of common correlative conjunctions.

Conjunctive Adverbs
The conjunctive adverbs such as however, moreover, nevertheless, consequently, as a result are used to create complex relationships between ideas. Refer to the section on Coherence: Transitions Between Ideas for an extensive list of conjunctive adverbs categorized according to their various uses and for some advice on their application within sentences (including punctuation issues).
