My favorite season:

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. So while the term is now widely used in the U.S., it is not exclusively American, nor is it American in origin.
