Word History of DECEMBER

The earliest Roman calendar had only ten months and began with the month of March. The tenth and last month was called in Latin December, a word which combines the Latin words for ten (decem), month (mens), and a final word-forming element -ri-. The name was kept—and eventually borrowed by English—after December became the last of twelve Roman months.
