conjunctions

You can use a conjunction to link words, phrases, and clauses, as in the following example:

I ate the pizza and the pasta.
Call the movers when you are ready.

Co-ordinating Conjunctions

You use a co-ordinating conjunction ("and," "but," "or," "nor," "for," "so," or "yet") to join individual words, phrases, and independent clauses. Note that you can also use the conjunctions "but" and "for" as prepositions.

In the following sentences, each of the highlighted words is a co-ordinating conjunction:

Lilacs and violets are usually purple.
In this example, the co-ordinating conjunction "and" links two nouns.

This movie is particularly interesting to feminist film theorists, for the screenplay was written by Mae West.
In this example, the co-ordinating conjunction "for" is used to link two independent clauses.

Daniel's uncle claimed that he spent most of his youth dancing on rooftops and swallowing goldfish.
Here the co-ordinating conjunction "and" links two participle phrases ("dancing on rooftops" and "swallowing goldfish") which act as adverbs describing the verb "spends."
