Updated: 2026-10-22

## Definition

to talk to someone in a calm, logical way to try and change their mind. You use this when someone is being difficult or emotional.

For teachers: to persuade someone through logical argument or rational discussion. The verb is intransitive and requires the preposition 'with' to introduce the person being addressed.

## Examples

- I tried to reason with him, but he wouldn't listen.
- When the toddler started crying in the supermarket, his mother tried to reason with him about why he couldn't have the toy.
- Diplomats spent hours attempting to reason with the rebel leaders, hoping that a logical appeal to their long-term interests would prevent further conflict.

## Pitfalls

- Not "I tried to reason him." but "I tried to reason with him." — The verb 'reason' requires the preposition 'with' when followed by the person being persuaded.

## Usage notes

- Always followed by the person you are trying to convince.
- Teaching tip: Contrast with 'argue with'; 'reason with' implies a calm, logical approach rather than a heated conflict.
