Plaster

Meaning: “Plaster” refers to a soft mixture used for coating walls and ceilings that hardens into a smooth surface (uncountable noun). It also means a medical paste or adhesive bandage applied to the skin for healing (countable or uncountable). As a verb, it means to cover or coat with this substance or to apply it thickly.

Pronunciation: In Received Pronunciation (UK), it’s /ˈplɑː.stə/ with stress on the first syllable. In US English, it’s /ˈplæs.tɚ/, rhyming with “master.” The ‘a’ sound varies regionally: long like “ah” in British English, short like “a” in American.

Morphology and Grammar Notes: Derived from Middle English “plaster,” from Latin “emplastrum” meaning bandage. Noun: countable (e.g., a plaster for walls) or uncountable (e.g., wall plaster). Plural: plasters. Verb: regular conjugation—plasters, plastering, plastered. No irregular forms; it’s transitive, requiring an object (e.g., plaster the wall).

Etymology: From Old English “plaster,” borrowed from late Latin “plastrum,” a shortened form of “emplastrum” (bandage). Reinforced in Middle English via Anglo-Norman “plastre.” The word evolved from medical use to building materials.

Short Interesting Facts: Plaster of Paris, a type of gypsum plaster, gets its name from the Montmartre quarries in Paris, France, where it was mined. Ancient Egyptians used plaster for mummies and pyramid interiors over 5,000 years ago.
