More Translations »

plaster (n.)

O.E. plaster "medicinal application," from V.L. plastrum, shortened from L. emplastra "a plaster" (in both the medical and building senses), from Gk. emplastron "salve, plaster" (used by Galen instead of more usual emplaston), from neut. of emplastos "daubed on," from en- "on" + plastos "molded," from plassein "to mold" (see plasma). The building sense is first recorded in Eng. c.1300, via O.Fr. plastre. Meaning "to bomb (a target) heavily" is first recorded 1915. Plaster of Paris (c.1462) originally was made from the extensive gypsum deposits of Montmartre in Paris. Plastered "drunk" is attested from 1912, perhaps from plaster in sense of "to apply a remedy to, to soothe," hence "to give compensation" (1891).
