This document discusses different types of conjunctions: - Coordinating conjunctions connect words or groups of the same type, such as nouns, verbs, or sentences. Examples include "and", "but", and "or". - Correlative conjunctions work in pairs to connect the same types of words. Examples include "both...and" and "either...or". - Subordinating conjunctions connect a dependent clause to an independent clause and show the relationship between them. Examples include "because", "after", and "since". The dependent clause comes first and is separated by a comma when the conjunction is placed at the beginning of the sentence.
