The Short Answer: Both terms originated in England, not America. "Autumn" comes from the Latin word autumnus and became popular in the 16th century. "Fall" is a shortening of the phrase "fall of the leaf," which showed up in 16th-century England. English settlers took both words to North America. There "fall" became the everyday word, while in Britain it faded and "autumn" became the standard.
- 📜 Oldest Name: "Harvest" (Old English hærfest).
- 🇬🇧 British Preference: Autumn (Latin origin).
- 🇺🇸 American Preference: Fall (Germanic origin).
- 📅 Meteorological Start: September 1st.
The Etymology of Fall and Autumn
The transition from summer to winter is one of nature’s most breathtaking displays. With fiery leaves carpeting the ground and crisp air hinting at the colder days ahead, this season goes by two names. But why the split?
Where "Autumn" Comes From
The word autumn comes from the Latin autumnus. Where the Romans got it is not certain: one idea is an Etruscan root, autu-, linked to the passing of the year. English picked the word up through Old French (autompne). A few early examples go back as far as the 12th century, and by the 16th century it was in common use.
How "Fall" Came Into Use
While autumn has an elegant history, fall emerged from practical linguistic evolution. In 16th-century England, expressions like "fall of the leaf" became common. This was eventually shortened to simply fall. When English settlers moved to the American colonies in the 17th century, they carried this term with them. After that the two countries drifted apart: in Britain "fall" slowly went out of use, in North America it became the normal word. Nobody has a proven reason why. It just stuck, a bit like a nickname.
🌾 The Original Name: "Harvest"
Before autumn or fall existed in English, the season was called Harvest. Rooted in the Old English hærfest, it reflected the season’s primary purpose: gathering crops. As society shifted from farms to cities, "Harvest" became associated with the act of gathering rather than the time of year, creating space for the new names to take over.
Scientific Definitions of the Season
Depending on who you ask, Fall starts at different times. Here is how scientists define it.
Begins with the Autumnal Equinox (on or around September 22). The sun is directly above the equator, creating equal day and night.
Begins on September 1st. Meteorologists use consistent 3-month blocks (September, October and November) because that makes seasonal statistics much easier to calculate, as NOAA's National Centers for Environmental Information explains.
Cultural Significance
Fall is deeply embedded in tradition. From Thanksgiving in North America to the Moon Festival in China, it is a time of gratitude. In literature, John Keats described it as a season of "mellow fruitfulness."
⚠️ Seasonal Weather Hazards
Fall is beautiful, but it brings specific risks. As the seasons change, clashing air masses can create severe storms. Understanding weather folklore like "Red Sky at Night" can help you predict these shifts during your autumn hikes. Also, be aware of heat lightning which may still occur in early fall.
Fun Facts About Fall
One of the most breathtaking spectacles is the vibrant foliage in regions like New England. The science behind this beauty lies in the breakdown of chlorophyll. As days shorten, green fades, revealing yellows (carotenoids) and reds (anthocyanins).

Also, as humidity drops in the fall, instruments can drift. Learn how to calibrate your hygrometer to ensure your indoor comfort data is accurate as you turn on the heat.

Frequently Asked Questions
Why do Americans say Fall?
It comes from the 16th-century English phrase "fall of the leaf". Settlers took the word to North America in the 17th century. There it became the everyday name for the season, while in Britain it went out of use.
When did "Harvest" stop being used?
Before the 16th century "harvest" was the usual English name for the season. As more people moved from farm work to towns, the word kept its meaning of gathering crops and lost its meaning as a time of year. "Autumn" and "fall" took its place.
