What does autumn mean?
Autumn is the season that follows summer and precedes winter, marked by shortening days, cooling temperatures, and the turning and shedding of leaves on deciduous trees. In the Northern Hemisphere it runs roughly from September to November, though in the Southern Hemisphere these months fall within spring instead. The word is used both literally, in weather reports, calendars, and descriptions of landscape, and figuratively, where 'the autumn of life' evokes a mature or declining stage of a person, an institution, or an era. Autumn carries strong cultural and poetic associations — harvest, mellow fruitfulness, nostalgia, and melancholy beauty — making it one of the most richly connotative season names. It is standard in British English, while American English typically uses 'fall' for the same season, reserving 'autumn' for formal or literary registers. The related adjective 'autumnal' describes things characteristic of the season, from colours and light to moods.
The season between summer and winter, characterized by cooling weather and falling leaves; roughly September to November in the Northern Hemisphere.
"Migrating birds pass through the valley every autumn."
Standard in British English; American English usually says 'fall'.
A late or declining stage of something, especially of a person's life.
"He wrote his finest poetry in the autumn of his years."
Literary and figurative; carries connotations of maturity and gentle decline.
Used when referring to multiple instances of the season, often to convey recurrence over the years.
"They returned to the lakeside cottage for many autumns."
English borrowed 'autumn' from Latin via French, yet Americans eventually abandoned it for plain old 'fall' — leaving Britain speaking Latin and America speaking Anglo-Saxon.

Etymology of autumn
Autumn entered Middle English in the late medieval period, borrowed from Old French 'autompne', which itself derives from Latin 'autumnus', the classical Roman name for the season. The ultimate origin of the Latin word is unknown, though it has been linked speculatively to Etruscan sources without firm evidence. The older English term for the season was simply 'harvest', and in North America 'fall' arose in the seventeenth century as a shortened form of 'fall of the leaf', gradually displacing 'autumn' in everyday use while it remained standard in Britain.
