Kids Definition

December

noun
De·​cem·​ber di-ˈsem-bər How to pronounce December (audio)
: the twelfth month of the year
Etymology

Middle English Decembre, December "last month of the year," from early French decembre (same meaning), from Latin December, literally, "tenth month," from decem "ten" — related to decimal, dime

Word Origin
In the first calendar used by the ancient Romans, the year began with the month of March. The Romans called the tenth month of the year December, using the Latin word decem, meaning "ten." When the word was borrowed into early French, it became decembre. That was also how it was first spelled when it came into Middle English. In time, however, the English word was changed to match the original Latin in spelling and in having a capital letter.
