## Definition

having the highest temperature compared to everything else. It can also describe something that is very popular or exciting right now.

For teachers: the superlative form of hot, indicating the maximum degree of thermal energy or, figuratively, the peak of current popularity and trendiness.

## Examples

- July is usually the hottest month of the year.
- The tech company just released its hottest new gadget, and thousands of people are already waiting in line.
- Climatologists confirmed that the previous decade was the hottest on record, prompting urgent discussions regarding global carbon emission targets and renewable energy transitions.

## Pitfalls

- Not "the most hottest day" but "the hottest day" — Short adjectives like 'hot' form the superlative by adding '-est'; using 'most' as well is a double superlative error.

## Usage notes

- Superlative form of the adjective 'hot'; requires the definite article 'the' when used before a noun.
