plaster: plaster: [OE] Like plastic, plaster comes ultimately from the Greek verb plássein ‘mould’. Combination with the prefix en- ‘in’ produced emplássein ‘daub on, plaster’. From its past participle emplastós was derived émplastron ‘medicinal application to the skin’, which reached Latin as emplastrum. Medieval Latin shortened it to plastrum, which Old English adopted as plaster. Its use for a ‘soft substance spread on walls, etc’ was introduced via Old French plastre in the 14th century.

plaster (n.): late Old English plaster "medicinal application," from Vulgar Latin plastrum, shortened from Latin emplastrum "a plaster" (in the medical as well as the building sense), from Greek emplastron "salve, plaster" (used by Galen instead of more usual emplaston), noun use of neuter of emplastos "daubed on," from en- "on" + plastos "molded," from plassein "to mold" (see plasma). The building construction material is first recorded in English c. 1300, via Old French plastre, from the same source, and in early use the English word often had the French spelling.
plaster (v.): "to coat with plaster," early 14c., from plaster (n.) and partly Old French plastrier "to cover with plaster" (Modern French platrer), from plastre (see plaster (n.). Related: Plastered; plastering. Figurative use from c. 1600. Meaning "to bomb (a target) heavily" is first recorded 1915. Sports sense of "to defeat decisively" is from 1919.
