This document defines and provides examples of different types of conjunctions and their functions. It discusses coordinating conjunctions such as "and", "but", and "or" which join elements of equal weight. Correlative conjunctions like "both...and" and "either...or" also join elements of equal weight. Subordinating conjunctions such as "although", "because", and "when" join two clauses by making one subordinate to the other. Finally, conjunctive adverbs like "moreover", "however", and "therefore" connect independent clauses and indicate comparisons, contrasts and other relationships between the clauses.
