Borrowed from French plaque (“plate, sheet (of metal); slab (of marble); bacteria on teeth”), from French plaquer, Middle French plaquer (“to plate”), from Middle Dutch placken (“to patch, beat metal into a thin plate”), from placke (“disk, patch, stain”), from Old Dutch *plagga (“patch”), from Proto-Germanic *plaggą (“patch”).
The word is cognate with Middle Low German placke, plagge (“small stain, scraps, rags, thin grass”), German Placken (“spot, patch”), Saterland Frisian plak, plakke (“a blow, slap”), Swedish plagg (“clothing, garment”). Compare plack.
