Preclude Someone From Doing vs. Preclude Someone To Do
Cambridge directly documents preclude + person + from + -ing as the action-prevention construction. Preclude also occurs with noun phrases and possibility expressions, but the cited evidence does not support person + to-infinitive as an equivalent.
Use “preclude someone from doing something” for the documented prevention construction; do not use “preclude someone to do” as its equivalent.
Key details
Choose the right form
| Meaning / situation | Form / construction | Decision |
|---|---|---|
| prevent a person from an action | preclude + person + from + -ing | Use the documented prevention construction. |
| exclude a possibility or outcome | preclude + noun phrase | A noun phrase is also possible in a different complement pattern. |
| person + to-infinitive as the prevention complement | not the supported equivalent | Do not substitute “preclude someone to do.” |
Quick tests
Meaning / construction test
Are you saying that something prevents a person from performing an action?
If yes: Use “preclude someone from doing something.”
If no: Use another documented “preclude” construction if you are naming a possibility or noun phrase rather than a person’s action.
Examples
The restriction precluded us from entering early.
“From” plus -ing expresses the prevented action.
The evidence does not preclude another explanation.
A noun phrase can follow “preclude” in a different construction.
The delay precluded the team from finishing on time.
The person/group plus “from” + -ing pattern expresses prevention.
Further guidance
Boundary
Preclude can also take a noun phrase or expressions such as “preclude the possibility”; those patterns do not create a person + to-infinitive complement.
Construction
Cambridge directly records “preclude someone from doing something” for preventing a person from an action.
Decision
Use “preclude someone from doing something” for the documented prevention construction; do not use “preclude someone to do” as its equivalent.
