spiel
"glib speech, pitch," 1896, probably from verb (1894) meaning "to speak in a glib manner," earlier "to play circus music" (1870), from Ger. spielen "to play," from O.H.G. spilon (cognate with O.E. spilian "to play"). The noun also perhaps from Ger. Spiel "play, game."

Yiddish - shpil, shpiln
