Compound Sentence with Transitional Word
When a transitional word joins two independent clauses, the usual pattern is a semicolon before the transitional word and a comma after it. (The common transitional words of this type are accordingly, consequently, furthermore, however, moreover, nevertheless, therefore.) The pattern looks like this:
Note: If the transitional word is separating independent clauses — each of which has its own subject and verb, and each of which could stand alone as a sentence — you may correctly use either a semicolon or a period to separate the independent clauses. Do not use the semicolon if the transitional word is not separating independent clauses.
