: the ninth month of the year

Etymology

Middle English Septembre "the month of September," from Old English September and early French Septembre (both, same meaning), both from Latin September "the seventh month," from septem "seven"

Word Origin

The ancient Romans originally used a calendar which began the year with the month of March. The seventh month of the year was called September, from septem, a Latin word meaning "seven." The name was spelled Septembre when it was borrowed from early French into Middle English, but eventually the English spelling was changed to that of the original Latin.
