Clauses
A clause is
a group of words that contains a verb (and usually other components too).
A clause may form part of a sentence or it may be a complete sentence in
itself.
For
example:
He was eating a bacon sandwich.
|
[clause]
|
She had a long career
|
but she is remembered mainly for one early work.
|
[clause]
|
[clause]
|
She is at home

Main
clause
Every sentence contains at least one main clause. A
main clause may form part of a compound
sentence or a complex
sentence, but it also makes sense on its own, as in this
example:
He was eating a bacon sandwich.
|
[main
clause]
|
The restaurant bill has
already been paid.
S P
Compound sentences are made up of two or more main clauses linked by a conjunction such asand, but, or so, as in the following examples:

Subordinate
clause
A subordinate
clause depends on a main clause for its meaning. Together with a main
clause, a subordinate clause forms part of a complex sentence. Here are
two examples of sentences containing subordinate clauses:
After we had had lunch,
|
we went back to work.
|
[subordinate
clause]
|
[main
clause]
|
I first saw her in Paris,
|
where I lived in the early nineties.
|
[main
clause]
|
[subordinate
clause]

·
After I
changed the APN, I unpluged my modem and waited for 5 minutes.
·
Before she
went to Jakarta, she got her flowers watered
·
As
soon as/once they finish filling the
questionnaire, I will process the data.
There are two main types of subordinate clause:
conditional clauses and relative clauses.
Conditional
clause
A conditional
clause is one that usually begins
with if or unless and describes something that is possible
or probable:
If it looks like rain
|
a simple shelter can be made out of a plastic sheet
|
[conditional
clause]
|
[main
clause]
|
I'll be home tomorrow
|
unless the plane's delayed for hours.
|
[main
clause]

(+) If I have free time,
I will go swimming.
(-) If you don’t finish your homework, your teacher will be angry.
(?) If they invite you, will you come?
(-) If you don’t finish your homework, your teacher will be angry.
(?) If they invite you, will you come?
Relative
clause
A relative clause is one connected to a main clause by
a word such
as which, that, whom, whose,when, where, or who:
I first saw her in Paris,
|
where I lived in the early nineties.
|
[main
clause]
|
[relative
clause]
|
She wants to be with Thomas,
|
who is best suited to take care of her.
|
[main
clause]
|
[relative
clause]
|
I was wearing the dress
|
that I bought to wear to Jo's party.
|
[main
clause]
|
[relative
clause]
|
Using
relative clauses
Have you ever wondered about when to
use that and when to use which or who in this
type of sentence? In fact, for much of the time that is interchangeable with
either of these words. For example:
You’re the only person who has ever listened
to me.
You’re the only person that has ever
listened to me.
It’s a film that should be seen by everyone.
It’s a film which should be seen by everyone
When referring to
something, rather than someone, that tends to be the usual choice in
everyday writing and conversation in British English. However, there is one
main case when you should not use that to introduce a relative
clause. This is related to the fact that there are two types of relative
clause: a restrictive relative clause and a non-restrictive
relative clause.
Restrictive relative clause
A restrictive relative
clause (also known as a defining relative clause) gives essential
information about a noun that comes before it: without this clause the sentence
wouldn’t make much sense. A restrictive relative clause can be introduced
by that, which, whose, who, or whom. You should not
place a comma in front of a restrictive relative clause:
√ She held out the hand
|
which was hurt.
|
√ She held out the hand
|
that was hurt.
|
[main
clause]
|
[restrictive
relative clause]
|
You can also leave
out that or which in some restrictive relative clauses:
√ It reminded him of the house
|
that he used to rent in Oxford.
|
√ It reminded him of the house
|
which he used to rent in Oxford.
|
√ It reminded him of the house
|
he used to rent in Oxford.
|
[main
clause]
|
[restrictive
relative clause]
|
Non-restrictive
relative clause
A non-restrictive relative clause (also called
a non-defining relative clause) provides extra information that could be
left out without affecting the
meaning or structure of the sentence. Non-restrictive relative clauses are
normally introduced by which, whose, who, or whom, but
never bythat. You should place a comma in front of them:
She held out her hand,
|
which Rob shook.
|
[main
clause]
|
[non-restrictive
relative clause]
|
If a non-restrictive relative clause is in the middle
of a sentence, you should put commas beforeand after it:
Bill,
|
who had fallen asleep on the sofa,
|
suddenly roused himself.
|
|
[non-restrictive
relative clause]
|
What
Are Clauses?
A clause is a group of words that includes a subject and
a verb.
A clause can be distinguished from a phrase, which does not contain a subject and a verb (e.g., in the afternoon, drinking from the bowl).
An independent clause can express a complete thought (and can be a standalone sentence). A dependent clause is usually a supporting part of a sentence, and it cannot stand by itself as a meaningful proposition (idea).

Examples
of Independent Clauses
Here are some examples of independent clauses
(shaded):
Tara ate a cheese roll after she watched the
news.
(Tara ate a cheese roll is an independent clause.
It works as a standalone sentence.)
Even though his mother was a driving
instructor, my cousin failed his driving test six times.
A computer once beat me at chess, but it was no match
for me at kick boxing. (Louis Hector Berlioz)
Examples
of Dependent Clauses
Here are the same examples with the dependent clauses
shaded:
Tara ate a cheese roll after she watched the
news.
(The clause after she watched the news is a
dependent clause. It does not work as a standalone sentence.)
Even though his mother was a driving instructor, my
cousin failed his driving test six times.
A computer once beat me at chess, but it was no
match for me at kick boxing.
These three dependent clauses (or subordinate
clauses as they're also called) could have been independent clauses.
However, the opening word(s) (in these examples after, Even though,
and but) turned them into dependent clauses. The opening words are known
as dependent words, the main type of which issubordinating
conjunctions.
How
Are Clauses Used in Sentences?
Clauses can play a variety of roles in sentences. A
clause can act as a noun, an adjective, or an adverb.
Noun
Clauses
I cannot remember what I said last night.
(In
this example, the clause acts like a noun.)
Compare the example above to this:
I cannot remember my speech.
(speech = noun)
I forgot the fact. (noun)
I forgot the fact. (noun)
I forgot it. (pronoun)
I forgot that the fact was very important. (noun
clause)
Adjective
Clauses
My dog, who usually refuses to go near the water,
dived in the canal to chase a water vole.
(In
this example, the clause acts like an adjective.)
Compare the example above to this:
My water-shy dog dived in the canal to chase
a water vole.
(water-shy =
adjective)
If an adjective clause could be removed without wrecking the sentence (i.e., it just adds additional information), then it should be offset with commas. (You could equally use brackets or dashes.) A clause which can be safely removed is called a non-restrictive clause. A restrictive clause, on the other hand, is one which cannot be removed because it's essential to the sentence. Restrictive clauses are not offset with commas.

For example:
The man who lives next door is getting
ruder.
(This is an example of a restrictive clause. You
cannot remove it. There are no commas.)
Councillor Simon Smith, who lives next door, is
getting ruder.
(This is an example of a non-restrictive clause. You
can remove it. It's just additional information. That's why there are commas
around it.)
Adverbial
Clauses
He lost his double chin after he gave up beer.
(In
this example, the clause acts like an adverb.)
Compare the example above to this:
He lost his double chin recently.
(recently =
adverb)
