- Old English spillan "destroy, kill," variant of spildan, from Proto-Germanic *spelthijanan (cf. Old High German spildan "to spill," Old Saxon spildian, Old Norse spilla "to destroy," Middle Dutch spillen "to waste"), from PIE *spel- "to split, break off" (cf. Middle Dutch spalden, Old High German spaltan "to split;" for further cognates, see spoil). Related: Spilled; spilling.
