This document discusses conjunctive adverbs, which are similar to conjunctions but typically join only sentences. Some common conjunctive adverbs include furthermore, moreover, however, nevertheless, nonetheless, therefore, consequently, hence, and thus. Conjunctive adverbs are more academic and formal than conjunctions. Examples are provided to show how conjunctive adverbs can join two sentences with different punctuation options, either with a semicolon or period between the sentences. The use of conjunctive adverbs avoids overusing conjunctions like "and" and "but" and allows for more sophisticated academic writing.
