Conjunctions are words that join words, phrases, or clauses together. Here are some examples:
* Coordinating conjunctions: and, but, or, nor, for, so, yet
* Subordinating conjunctions: because, although, since, while, if, unless, until, after, before, as
* Correlative conjunctions: both...and, either...or, neither...nor, not only...but also
