1. It has two names

The season is known as both “fall” and “autumn.” The word “autumn” comes from Latin, while “fall” originated in 17th-century Britain as a shortening of the phrase “fall of the leaf.” While both are correct, “fall” is more commonly used in American English.

3. Red and purple leaves are a sweet bonus

Unlike the yellows and oranges, the beautiful red and purple hues in some fall leaves are created by sugars trapped in the leaves. Cool nights and sunny days cause these sugars to produce vibrant pigments called anthocyanins.
