Updated: 2026-07-27

## Definition

to believe that someone or something is reliable, honest, or effective. You use this when you feel confident in a person's character or a plan's success.

For teachers: to place confidence in the reliability, truth, or ability of someone or something. Always takes a noun-phrase object.

## Examples

- I trust in your ability to finish the job.
- The community continues to trust in the local government to manage the new infrastructure project effectively.
- While the initial data seemed promising, the lead researchers were hesitant to trust in the findings until they had completed a secondary peer-review process.

## Pitfalls

- Not "I trust you in" but "I trust in you" — The preposition 'in' must precede the object; it cannot be placed after the object.

## Usage notes

- The phrasal verb is transitive and requires a direct object.
