## Definition

to suddenly realize something or understand a fact for the first time.

For teachers: to become evident or understood by someone, typically after a period of confusion or ignorance. The subject is usually the realization or fact, while the person experiencing it is the object of the preposition 'on'.

## Examples

- It finally dawned on me that I was in the wrong room.
- As she looked at the empty driveway, it slowly dawned on her that her car had been stolen while she was in the shop.
- Only after reviewing the financial discrepancies for a third time did it dawn on the auditor that the CEO had been embezzling funds for years.

## Pitfalls

- Not "I dawned on the truth." but "The truth dawned on me." — the person who realizes the fact must be the object of the preposition 'on'.

## Usage notes

- usually used with 'it' as a dummy subject followed by a 'that' clause.
- Teaching tip: use the metaphor of the sun rising to explain how an idea becomes clear in the mind.
