Compel Someone To Do vs. Compel Doing
Cambridge documents compel + object + to-infinitive for forcing a person to act and separate direct-object senses such as compelling a change or reaction. Compel can take noun objects in other senses, so distinguish “force a person to act” from “cause a result/reaction.”
Use “compel someone to do something” when the object is the person forced to act; do not treat a bare -ing phrase as the interchangeable complement.
Key details
Choose the right form
| Meaning / situation | Form / construction | Decision |
|---|---|---|
| force a person to act | compel + person + to-infinitive | Use the object + to-infinitive pattern. |
| cause or require a result/reaction named by a noun object | compel + noun object | Treat this as a separate direct-object sense, not a gerund alternative to the person pattern. |
Quick tests
Object-pattern test
Is the grammatical object the person who is being forced to act?
If yes: Use “compel someone to do something.”
If no: If “compel” directly takes a result or reaction as its object, analyze that separate sense instead.
Examples
The court order compelled the company to provide the records.
The company is the object forced to act.
The evidence compelled a change in policy.
Here “a change” is a direct noun object describing the result.
Do not treat a bare -ing phrase as interchangeable with the documented object + to-infinitive pattern.
The reviewed source distinguishes the person-action pattern from other direct-object uses.
