A conjunction is a word used to connect words, phrases, or clauses within a sentence. There are three main types of conjunctions: coordinating conjunctions, subordinating conjunctions, and correlative conjunctions.
Coordinating conjunctions are used to connect words, phrases, or independent clauses that are of equal importance within a sentence. The most common coordinating conjunctions are: and, but, or, nor, for, yet, so.
Subordinating conjunctions are used to join an independent clause with a dependent clause. Some common subordinating conjunctions include: after, although, because, before, if, since, until, when, while.
Correlative conjunctions are used in pairs to join words or phrases that carry equal importance within a sentence. Some examples of correlative conjunctions are: either...or, neither...nor, both...and, not only...but also, whether...or.
