Clauses

What is a clause?

A clause is a part of a sentence. There are two main types: independent (main clauses), dependent (subordinate clauses).

Independent Clauses

An independent clause is a complete sentence; it contains a subject and verb and expresses a complete thought in both context and meaning.

For example: The door opened.

Independent clauses can be joined by a coordinating conjunction to form complex or compound sentences.

Co-ordinating Conjunctions

and but for

or nor so

yet

For example: Take two independent clauses and join them together with the conjunction and: " The door opened." "The man walked in." = The door opened and the man walked in.

Dependent Clauses

A dependent (subordinate) clause is part of a sentence; it contains a subject and verb but does not express a complete thought. They can make sense on their own, but, they are dependent on the rest of the sentence for context and meaning. They are usually joined to an independent clause to form a complex sentence.

Dependent clauses often begin with a a subordinating conjunction or relative pronoun (see below) that makes the clause unable to stand alone.

Subordinating Conjunctions

after although as because

before even if even though if

in order that once provided that rather than

since so that than that

though unless until when

whenever where whereas wherever

whether while why

Relative Pronouns

that which whichever

who whoever whom

whose whosever whomever

For example:

The door opened because the man pushed it.

Dependent clauses can be nominal, adverbial or adjectival.

A nominal clause (noun clause) functions like a noun or noun phrase. It is a group of words containing a subject and a finite verb of its own and contains one of the following: that | if | whether

For example:

• I wondered whether the homework was necessary.

Noun clauses answer questions like "who(m)?" or "what?"

An adverbial clause (adverb clause) is a word or expression in the sentence that functions as an adverb; that is, it tells you something about how the action in the verb was done. An adverbial clause is separated from the other clauses by any of the following subordinating conjunctions: after | although | as | because | before | if | since | that | though | till | unless | until | when | where | while

For example:

• They will visit you before they go to the airport.

Adverbial clauses can also be placed before the main clause without changing the meaning.

For example:

• Before they go to the airport, they will visit you.
