Respuesta :
Conjunctive adverbs are not strong enough to join independent clauses without supporting punctuation. Use a comma if a conjunction such as and, but, or, or so appears between the conjunctive adverb and the first clause.
Answer:
A conjunctive adverb connects two independent clauses or sentences. Typically, adverbs modify other words (verbs, adjectives, and other adverbs). Conjunctive adverbs, however, are used to modify two independent clauses and join them together, behaving more like coordinating conjunctions.
