Xmas is a common abbreviation of the word Christmas .originated as handwriting abbreviations for the typical pronunciation /?kr?sm?s/. The "-mas" part is from the Latin-derived Old English word for Mass,[1] while the "X" comes from the Greek letter Chi, which is the first letter of the Greek word ??????? which comes into English as "Christ".There is a common misconception that the word Xmas stems from a secular attempt to remove the religious tradition from Christmas[3] by taking the "Christ" out of "Christmas", but its use dates back to the 16th century.www.dnaenglish.comthe best way to learn english language. the best way to learn english speaking. the best way to learn english vocabulary. the best way to learn speaking english.
