Scare Someone Into Doing vs. Scare Someone To Do
Cambridge directly documents scare + object + into + -ing for causing or persuading someone to act by frightening them. Scare has other constructions for producing fear, including scare + object and phrasal uses such as scare away/off; those meanings should not be collapsed into the complement comparison.
Use “scare someone into doing something” for the directly documented action pattern; this evidence does not establish “scare someone to do” as the parallel complement.
Key details
Choose the right form
| Meaning / situation | Form / construction | Decision |
|---|---|---|
| frighten someone so that the fear causes or pressures an action | scare + person + into + -ing | Use the directly documented action pattern. |
| simply make someone afraid | scare + person | This is a separate construction and does not require an action complement. |
| drive or cause someone/something to leave | scare away / scare off | These phrasal uses are separate from the “into + -ing” comparison. |
Quick tests
Meaning / construction test
Are you naming an action someone took because they were frightened or pressured by fear?
If yes: Use “scare someone into doing.”
If no: Use the construction for the intended fear sense; the reviewed evidence does not establish “scare someone to do” as the parallel complement.
Caveat: This guide compares the directly documented action complement. Other ordinary constructions such as “scare someone” and “scare away/off” remain separate.
Examples
The warning scared them into leaving early.
“Into + -ing” names the action caused by fear.
The noise scared the birds away.
This is the separate phrasal construction “scare away.”
The sudden bang scared me.
Here “scare” directly takes the person affected, with no action complement.
