What is the X in X-mas?
"glib speech, pitch," 1896, probably from verb (1894) meaning "to speak in a glib manner," earlier "to play circus music" (1870), from German spielen "to play," from Old High German spilon (cognate with Old English spilian "to play"). The noun also perhaps from German Spiel "play, game."
