This document discusses different types of modifiers - misplaced, dangling, and squinting modifiers - and provides examples to illustrate each. A misplaced modifier is one that is not placed next to the word it modifies. A dangling modifier does not logically refer to any word in the sentence. A squinting modifier seems to modify two words at the same time, causing confusion. The document provides examples from student essays that demonstrate misplaced and dangling modifiers, resulting in humorous or nonsensical meanings. It encourages readers to check their own writing for these types of errors and provides practice examples to correct.
