Word Nuance & Usage

In British and Commonwealth English, 'autumn' is the standard everyday word for this season, whereas in North American English, 'fall' is more common in casual speech and 'autumn' carries a slightly more formal or poetic tone.

Word Origin & Etymology

Borrowed in the late 14th century from Old French 'autompne', from Latin 'autumnus', a word of uncertain, possibly Etruscan, origin that gradually replaced the native Old English 'hærfest' (harvest) as the primary name for the season.
