One of the three types of conjunctions is the coordinating conjunction. We use a coordinating conjunction to join parts of a sentence that are equal in form, or parallel. Parts of sentences, such as words, phrases, and clauses, are called elements. A coordinating conjunction connects a word to a word, a phrase to a phrase, or a clause to a clause. When joined by a conjunction, they are called compound elements.
Here are the common coordinating conjunctions:
and but or nor for yet so
They may join a word to another word:
aunt and uncle
Rachel or Leah
