Planish

Part of speech: verb

Pronunciation: /ˈplænɪʃ/

Definitions

1. To smooth and flatten a metal surface by carefully hammering it to remove irregularities
2. The process of shaping metal to an even surface by repeatedly striking it with a hammer
3. To finish a piece of metal by gently beating it so that the surface becomes flat and smooth

Etymology: Metalworkers have a specific word for the final, careful tapping that leaves a sheet smooth, and it comes from the Latin adjective "planus", meaning "flat". The English verb took the Latin root and attached the suffix "-ish", the same ending found in words like "polish" and "finish", so the term describes the act of making something flat through hammering rather than cutting or grinding. The connection to "plane" is worth noting. Both "planish" and "plane" trace back to "planus", but they reached English along different routes and now describe very different tools and actions. "Plane" is the flat surface itself, while "planish" names the process of bringing a metal surface toward that flatness by hand.
