“However” and Other Conjunctive Adverbs
Conjunctive adverbs include however, therefore, thus, furthermore, and others.
If you use a conjunctive adverb to join two independent clauses (compound sentence), then use a semicolon, followed by the conjunctive adverb, followed by a comma:
The committee had heard these arguments before; therefore, it turned its attention to other matters. The agency trusted the report; however, the report proved faulty in its scientific method.Common Mistake
One of the most common mistakes in writing involves the use of a comma (not a semicolon) and a conjunctive adverb to join independent clauses:
Wrong: The agency trusted the report, however the report proved faulty in its scientific method. Right: The agency trusted the report; however, the report proved faulty in its scientific method.
