## Definition

in a way that is not correct, honest, or suitable for a situation. You use this when someone does something the wrong way or breaks a rule.

For teachers: in a manner that is incorrect, unsuitable, or dishonest. Often describes actions that violate formal procedures, social norms, or technical requirements.

## Examples

- The machine broke because it was used improperly.
- The committee found that the funds had been handled improperly, leading to a full investigation of the department's finances.
- If the evidence is collected improperly by the authorities, the judge may rule it inadmissible during the trial, regardless of its potential relevance to the case.

## Pitfalls

- Not "He behaved improper during the meeting." but "He behaved improperly during the meeting." — Learners often use the adjective 'improper' when the adverbial form 'improperly' is required to modify a verb.

## Usage notes

- Typically follows the verb or the direct object it modifies.
