## Definition

to fall asleep quickly and without meaning to, especially while you are sitting in a chair. You use this when someone is very tired or bored.

For teachers: To fall asleep involuntarily, typically while in a seated position. The verb is intransitive and often functions as a slang term for the sedative effects of narcotics or extreme physical exhaustion.

## Examples

- He was so tired that he started to nod out during the movie.
- After working a double shift, Sarah found herself nodding out on the bus ride home.
- The professor's lecture was so monotonous that several students in the back row began to nod out despite the looming final exam.

## Pitfalls

- Not "He nodded out to show he agreed with me." but "He nodded to show he agreed with me." — 'Nod out' refers to falling asleep, whereas 'nod' refers to the head gesture for agreement.

## Usage notes

- This phrase is informal and usually describes someone falling asleep while sitting up.
- Teaching tip: Contrast with 'nod off'; while both mean falling asleep, 'nod out' is more informal and can sometimes imply a drug-induced stupor.
