Dangling Modifiers: The Rules Explained Simply
The essential rules of dangling modifiers with examples you can apply immediately.
The core idea behind dangling modifier
Most grammar rules are simpler than they look. Dangling modifier comes down to a descriptive phrase with no clear word to attach to in the sentence, and once that idea clicks, the details fall into place.
A dangling modifier is a word or phrase, often at the start, that does not clearly modify any word in the sentence. Walking down the street, the trees were beautiful leaves the walker dangling.
What follows is the short list of rules that cover almost every case you will meet in everyday writing.
An opening -ing phrase almost always needs the doer right after the comma, so name the person or thing acting.
Rewriting the phrase as a full clause with its own subject is the safest fix when the doer is unclear.
To test for a dangler, read the opening phrase and the next word together and see if they make sense.
The rules, in plain terms
- An opening phrase must be followed by the word it modifies.
- If the doer is missing, add it right after the comma.
- Rewrite the phrase as a full clause with its own subject.
- Keep modifiers close to the word they describe.
- Read the opening phrase and the next word together to test for sense.
