independent clause A word group with a subject and a predicate that can stand alone as a separate sentence.
Although two independent clauses could be separated by a period, the semicolon tells the reader that they are closely related, emphasizing the restatement or sharpening the contrast.
Note: When the independent clauses are linked by and, but, or another coordinating conjunction, use a comma rather than a semicolon (see P1-a) unless the independent clauses include internal punctuation (see P3-c).
