What is a conjunction?

Conjunctions are words that join together other words or groups of words.

A coordinating conjunction connects words, phrases, and clauses of equal importance. The main coordinating conjunctions are and, or, and but.

When placed at the beginning of a sentence, a coordinating conjunction may also link two sentences or paragraphs.

A subordinating conjunction introduces a subordinate clause (a clause that does not form a simple sentence by itself) and joins it to a main clause (a clause that can be used as a simple sentence by itself).

Some conjunctions are used in pairs. The most common pairs are either ... or, both ... and, neither ... nor, and not only ... but (also).

Some adverbs, such as afterwards, consequently, for example, however, nonetheless, and therefore, act like conjunctions by linking either two main clauses separated by a semicolon, or two separate sentences. They express some effect that the first clause or sentence has on the second one.
