Is It 'Autumn' or 'Fall'? | Merriam-Webster

Autumn and fall are used interchangeably as words for the season between summer and winter. Both are used in American and British English, but fall occurs more often in American English. Autumn is considered the more formal name for the season.

The older of the two words is autumn, which first came into English in the 1300s from the Latin word autumnus.
