The document discusses different types of modifiers and provides examples of each:
1) Limiting modifiers like "just" and "only" must be placed directly before the word they modify to avoid confusion.
2) "Squinting modifiers" that seem to modify two words at once can be clarified by placing the modifier next to the intended word.
3) "Misplaced modifiers" are out of place and often result in unintended humor, so they need to be moved next to the words they modify. Fixing the placement of modifiers is important to ensure clear meaning.
