patchとは

意味・読み方・使い方

語源 1

From Middle English patche, pacche, of uncertain origin. Perhaps an alteration of earlier Middle English placche (“patch, spot, piece of cloth”) (for loss of l, compare pat from plat, fag from flag, etc.), probably from 古期英語 *plæċċ, *pleċċ (“a spot, mark, patch”), from Proto-Germanic *plakjō (“spot, stain”), related to Middle English plecke (whence dialectal English pleck (“plot of ground, patch”)), West Frisian plak (“place, spot”), Low German Plakk, Plakke (“spot, piece, patch”), Dutch plek (“spot, place, stain, patch”), Dutch plak (“piece, slab”), Swedish plagg (“garment”), Faroese plagg (“cloth, rag”).

Alternatively, perhaps a variant of Middle English pece (“piece”), from Old French pieche (“piece”), from Vulgar Latin *pettia, probably from Gaulish pettsi (“piece, bit”). Compare also Old Occitan petaç (“patch”).
