Conjunctive Adverbs
You can use a conjunctive adverb to join two clauses together. Some of the most common conjunctive adverbs are "also," "consequently," "finally," "furthermore," "hence," "however," "incidentally," "indeed," "instead," "likewise," "meanwhile," "nevertheless," "next," "nonetheless," "otherwise," "still," "then," "therefore," and "thus." A conjunctive adverb is not strong enough to join two independent clauses without the aid of a semicolon.
