## Definition

the lowest possible temperature compared to everything else. You use this to describe the most freezing day or place.

For teachers: the superlative form of 'cold'; representing the lowest temperature in a specific group or range. Functions as the extreme point on a scale of thermal intensity.

## Examples

- January is usually the coldest month of the year.
- The researchers recorded the coldest temperature ever measured on the planet at a remote station in Antarctica.
- Even in the coldest reaches of the deep ocean, specialized organisms have evolved to thrive in temperatures that would prove fatal to most terrestrial life forms.

## Pitfalls

- Not "the most coldest day" but "the coldest day" — Short adjectives like 'cold' form the superlative by adding '-est' — do not use 'most' with the '-est' ending.

## Usage notes

- Superlative form; typically preceded by the definite article 'the'.
