A conjunction is a word that joins two or more words, phrases, or clauses. There are three kinds of conjunctions: coordinating, subordinating, and correlative.
There are only seven coordinating conjunctions. They are for, and, nor, but, or, yet, and so. Coordinating conjunctions join together parts of a sentence that are the same. For example, “Would you like pie or cake?” or, “John likes taking walks and riding his bike.”
