A conjunction is a word (e.g., as and, but, or) used to connect words or phrases and in particular, clauses. Conjunctions are described as coordinating conjunctions, subordinating conjunctions, or correlative conjunctions.
A. Coordinating Conjunctions Words that join like with like, such as a noun with another noun, an adjective with another adjective, an adverb with another adverb, etc. (e.g., a fork and a knife, hot but dry, quickly but quietly, Jack and Jill), or an independent clause with an independent clause, are called coordinating conjunctions. They include and, but, for, or, and yet.
