SEMICOLON

The punctuation mark used to indicate a major division in a sentence where a more distinct separation is felt between clauses or items on a list than is indicated by a comma, as between two clauses of a compound sentence.

Use the semicolon to link independent clauses not joined by a coordinating conjunction. Semicolons should join only those independent clauses that are closely related in meaning.
