where did the word christmas originate from

The word "Christmas" comes from the Old English term "Cristes-messe", which literally means "the Mass of Christ." The word was first recorded in English around the 11th century, and it has been used to refer to the celebration of the birth of Jesus Christ ever since. The word has evolved over time and has become associated with the holiday season, which includes not only the celebration of Christmas but also the winter solstice and the New Year.
