Xmas has been used for hundreds of years in religious writing, where theX is understood to represent a Greek chi, the first letter of &S{C}&S{i}&S{s}&S{t}&S{o}&S{z}, .Christ.;in this use it is parallel to other forms likeXtian, .Christian.. But the letterX, or especially x, is nowadays more frequently interpreted as a mathematical variable than as a Greek letter, as indicated by the common pronunciation of the formXmas as (μks.m…s). Thus, while the word is etymologically innocent of the charge that it omits Christ from Christmas,it is now generally understood only as an informal shortening.In an earlier survey 88 percent of the Usage Panel rejected the use ofXmas in writing.
Xmas 在宗教作品中已用了幾百年， X 用來表示希臘字母chi， 是&S{C}&S{i}&S{s}&S{t}&S{o}&S{z}的第一個(gè)字母，意為.耶穌.；在這種用法中，它與其他形式相似,如Xtian, .教會的.。 但是字母X， 尤其是 x， 現(xiàn)在更常見的是當(dāng)作數(shù)學(xué)變量，而不是希臘字母， 因?yàn)樵摲?strong>Xmas 發(fā)音已普遍為(μks.m…s)。 因此,當(dāng)這個(gè)單詞從詞源學(xué)上把Christ從Christmas中省掉是合乎規(guī)則的，現(xiàn)在該詞已被廣泛看作一個(gè)非正式的縮寫形式。在早期的調(diào)查問卷中，有百分之八十八的用法使用小組成員拒絕在作品中用Xmas
