Xmas

You can thank the Greeks for calling Christmas “Xmas”. In Greek, the word for “Christ” starts with the letter Chi, which looks like an X in the Roman alphabet.

Xmas (also X-mas) is a common abbreviation of the word Christmas. It is sometimes pronounced , but Xmas, and variants such as Xtemass, originated as handwriting abbreviations for the typical pronunciation . The "X" comes from the Greek letter Chi, which is the first letter of the Greek word Christós (Greek: Χριστός), which became Christ in English. The suffix -mas is from the Latin-derived Old English word for Mass.There is a common misconception that the word Xmas stems from a secular attempt to remove the religious tradition from Christmas by taking the "Christ" out of "Christmas", but its use dates back to the 16th century. == Style guides and etiquette == "Xmas" is deprecated by some modern style guides, including those at the New York Times, The Times, The Guardian, and the BBC. Millicent Fenwick, in the 1948 Vogue's Book of Etiquette, states that "'Xmas' should never be used" in greeting cards. The Cambridge Guide to Australian English Usage states that the spelling should be considered informal and restricted to contexts where concision is valued, such as headlines and greeting cards. The Christian Writer's Manual of Style, while acknowledging the ancient and respectful use of "Xmas" in the past, states that the spelling should never be used in formal writing. == History == === Use in English === Early use of "Xmas" includes Bernard Ward's History of St. Edmund's college, Old Hall (originally published circa 1755). An earlier version, "X'temmas", dates to 1551.
