## Definition

having the least space or movement, or holding most firmly. You use it to compare three or more things, like clothes, lids, or rules.

For teachers: superlative of 'tight'; expressing the greatest degree of firmness, closeness of fit, or strictness within a compared set.

## Examples

- I wear my tightest shoes today.
- The plumber checks every joint and leaves the tightest seal on the main pipe.
- Among all the border controls introduced that year, the tightest restrictions applied to night flights, where even minor delays triggered full security reviews.

## Pitfalls

- Not "the most tightest" but "the tightest" — Do not add 'most' before a superlative ending in '-est' — 'tightest' already means the highest degree.

## Usage notes

- Superlative of 'tight'; normally preceded by 'the' when comparing a defined set.
