## Definition

having more body fat or being thicker than someone or something else. It is the form of 'fat' you use when comparing two things.

For teachers: the comparative form of 'fat'; having a greater amount of adipose tissue or a larger circumference than another entity.

## Examples

- The cat got fatter after we started feeding it more treats.
- This year's harvest produced much fatter pumpkins than the ones we grew last summer.
- While the older model was slim and portable, the newer version is significantly fatter due to the inclusion of a much larger internal battery.

## Pitfalls

- Not "more fatter" but "fatter" — One-syllable adjectives form the comparative by adding '-er'; using 'more' with the '-er' suffix is a double comparison error.

## Usage notes

- Comparative adjective; typically followed by 'than' when making a direct comparison.
