what is xmas mean

"Xmas" is a shortened version of the word "Christmas." It is a common abbreviation used to refer to the holiday, and is derived from the Greek word "Christos," meaning "anointed one" or "Messiah." Over time, the "X" became associated with the cross on which Jesus Christ was crucified, and the "mas" portion comes from the Latin word "massa," meaning "the Mass," which is the religious ceremony performed in honor of Christ's death and resurrection. So "Xmas" is a short way of saying "Christmas," or "the Mass of Christ."
