Autumn vs. fall
Fall and autumn are both accepted and widely used terms for the season that comes between summer and winter. Some who consider British English the only true English regard fall as an American barbarism, but this attitude is not well founded. Fall is in fact an old term for the season, originating in English in the 16th century or earlier. It was originally short for fall of the year or fall of the leaf, but it commonly took the one-word form by the 17th century, long before the development of American English.
Autumn came to English from the French 'automne' in the 15th or 16th century, but it didn’t gain prominence until the 18th century. After that, while fall became the preferred term in the U.S., autumn became so prevalent in British English that fall as a term for the season was eventually considered archaic. However nowadays British people, too, use the term 'fall' by a significant margin
