The modifier must match the product being manufactured.

Synonym discussion

Sense: noun/1

All four words refer to devices that crush or grind grain, but they differ in scope and specificity. 'Mill' (noun/1) is the broadest term — it can describe any building or machine that grinds grain into flour, regardless of power source. 'Grinder' is less common for buildings and usually refers to the mechanical device itself rather than the structure housing it; you might have a 'coffee grinder' on your kitchen counter, not a 'coffee mill' in most modern homes. 'Watermill' and 'windmill' are subtypes that specify the energy source — a watermill uses flowing water via a wheel, while a windmill uses blades turned by the wind. For example: 'The watermill next to the stream has been grinding flour since 1750' versus 'A windmill needs a breezy location to operate.'. The narrower terms help the listener picture the scene more precisely.

Etymology

LatinOld EnglishMiddle EnglishEnglish

The word 'mill' comes from Old English 'mylen', which was borrowed from Latin 'molina' (a mill), itself from 'mola' (a millstone). The Latin root traces back to 'molere', meaning 'to grind'. The verb sense 'to mill about' (move aimlessly) appeared in the 1800s, likely from the image of mill stones turning in a circle or sheep milling in a pen.
