Word History of OCTOBER
The earliest Roman calendar had only ten months and began with the month of March. The eighth month was called in Latin October, a word that combines the number octo, “eight,” with the element -ber found in September, November, and December. The name was kept—and eventually borrowed by English—after October became the tenth of twelve Roman months.
