Etymology

PIE word *dóru From Christmas + tree, a calque of German Weynacht Baum (obsolete, 17th c.), Weihnachtsbaum, from Weynacht, Weihnacht (literary or poetic variant of Weihnachten (“Christmas”)) + -s- (genitive interfix) + Baum (“tree”). The custom of Christmas trees was adopted in the United Kingdom from Germany in the 19th century, having been popularized by their use by the royal family during the reign of Queen Victoria from 1837 to 1901. Sense 3 (“Christmas party”) refers to the fact that there is usually a Christmas tree (sense 1) at the event.
