To me, the verb "to ground" seems inappropriate for this site, and I'd normally consider it simply a minor mistake or typo, but in What gives Turkish coffee that unique "quality"? it appears in the original question, in two answers, and in a comment:
OP:
- grounded coffee
- I asked the seller to ground my coffee
Answer 1:
- finely grounded
- after the grounding
- the finer the grounding
Answer 2:
- very fine grounded
- fine grounded coffee
- it is grounded so fine
Comment:
- other 'turkish' grounded coffee
Other than this one word, all of the submissions are written in good English, so its usage seems to be deliberate.
I know that there is a verb "to ground" in electrical technology, but is there some coffee-technical verb "to ground" that I haven't heard of before?
