This document provides guidance on using semicolons, dashes, and hyphens in punctuation. It explains that semicolons can be used to connect two independent clauses that are closely related, or to separate complex items in a list. Dashes come in three lengths - hyphens, en dashes, and em dashes - and each has a specific purpose like combining words, indicating date ranges, or setting off clauses within sentences. Examples are given for correct usage of each punctuation mark over commas. The document concludes with a practice problem identifying which punctuation is needed in sample sentences.
