Dangling Modifiers: Examples & How to Fix It
A modifier must clearly attach to the word it describes. A dangling modifier opens with a description (“Walking to school,”) but the noun that follows isn’t the one doing it (“the rain started”) — so it seems to modify the wrong thing.

How it works
- 1Spot the pattern. Check the opening phrase and ask “who or what is doing this?” If the noun immediately after the comma isn’t the answer, the modifier dangles.
- 2Apply the rule. Either name the right subject right after the comma, or rewrite the modifier as a full clause. “Walking to school, the rain started” → “Walking to school, I got caught in the rain.”
- 3Check your sentence. Paste your text into the grammar checker below — it flags the issue and shows the correction.
- 4Re-read it. Read the corrected version aloud to confirm it says exactly what you meant.
The rule
An introductory modifier (often an -ing or -ed phrase before the first comma) must describe the subject that comes right after the comma. If it doesn’t, the modifier “dangles”.

The most common mistake
Leaving the doer out so the sentence literally says something absurd — “After reading the book, the movie was disappointing” (the movie didn’t read the book). If you’re not sure whether your sentence has the problem, paste it into the checker above — it catches this and explains the fix in plain language.

An opening description that doesn’t logically attach to the subject that follows — e.g. “Running late, the bus was missed.” The bus wasn’t running late; you were.
Which sentence contains a dangling modifier?
The one whose introductory phrase describes a doer who never appears as the subject. Fix it by putting the real doer right after the comma.
