spat: English has three words spat (not counting the past form of spit). The oldest, ‘young of an oyster or similar shellfish’ [17], comes from Anglo-Norman spat, but the origins of that are unknown. Spat ‘shoe covering’ [19] is short for the earlier spatterdash [17]. This was a compound formed from spatter [16] (a word based ultimately on the sound of spattering) and dash (used here in the now archaic sense ‘splash violently’). Spat ‘tiff’ [19] originated in the USA, but its ancestry is not known.
