stucco
Stucco (noun) means a mix of binder and gritty material spread over indoor walls or shaped into indoor mouldings.
Etymology
Borrowed from Italian stucco (“coating made of pulverised gypsum, plaster, stucco”) from Old Italian stucco, from Lombardic stucki, *stucchi (“crust, fragment, piece”) from Proto-Germanic *stukkiją (“stump, piece”), from Proto-Indo-European *(s)tewg- (“to shock, butt, impact”). Akin to German Stück (“piece”), Old Saxon stukki (“piece, fragment”) and Old English stycce. Related to stock.
