This document discusses dangling and misplaced modifiers. It defines modifiers as words that identify or describe another word, usually a noun. Dangling modifiers occur when the word being modified is not present in the sentence. Misplaced modifiers appear to modify the wrong word because they are placed too far from the word they are intended to modify. The document provides examples of dangling and misplaced modifiers and how to correct them by moving the modifier closer to the word it modifies or adding the missing subject. It emphasizes that modifiers should be placed directly before or after the word they describe to avoid confusion. Practice exercises are assigned to reinforce these concepts.
