Coordinating Conjunctions

When most people think of conjunctions, they are usually thinking of the coordinating variety. The most common ones include and, but, or, and so. Coordinating conjunctions join words or groups of words that are equal in rank grammatically. For instance, in the following sentence the two nouns are separated with a coordinating conjunction.

Subordinating Conjunctions

Subordinating conjunctions, on the other hand, connect grammatical structures (usually clauses) of unequal rank. A subordinating conjunction introduces a clause that is dependent on the main clause. The dependent clause can be introduced preceding the main clause in an introductory role, or it may follow the main clause to add meaning to the sentence. Some common subordinating conjunctions include although, as, before, until, when, and while.
