Conjunctions

The thing I learned today is the classification of conjunctions.

• A coordinating conjunction (which I knew about) joins two main clauses, such as "I saw the bird and she saw the cat."  Examples are: and, but, or, yet, as soon as.
• A subordinating cunjunction (which I'd forgotten) joins a subordinate (or dependent) clause to a main clause, such that one of the clauses is given more importance, as in "Although I saw the bird, she saw the cat." Examples are: after, though, unless, until, while, if.
• A correlative conjunction (new to me!) is a pair of words such as either.. or, neither... not, and not only... but also, which joins two clauses, as in "Neither she nor I saw any animals."
