# optional

adjective (optional)

«optional» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

Something you can choose to do or have, but you do not have to. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/O/optional/#m1)

### In the lessons

In school, optional homework or optional questions are your choice; compulsory ones are not. In maths or tests «optional» extension tasks give extra challenge. In everyday life and shopping, extras like sauce or gift wrapping may be optional and sometimes cost more.
