October

noun
Oc·​to·​ber äk-ˈtō-bər How to pronounce October (audio)
: the tenth month of the year
Etymology

Middle English October, Octobre "the tenth month," from Old English October and early French octobre (both, same meaning), both from Latin October "the eighth month," from octo "eight"

Word Origin
According to its origin, the name October, which we know as the tenth month of the year, really means "eighth month." In the first calendar used in ancient Rome, the year had only ten months, starting in March and ending in December. The extra period between December and March was not considered part of the series of months. Later, when two extra months were added to the calendar, October became the tenth month but kept its old name. The Latin name came into Old English as october and into early French as octobre. It was spelled both ways in Middle English. But in time the influence of Latin fixed the spelling as october.
