Do you know about grinding? I know about grinding.
Grinding is taking a count noun, say, “chicken” or “fir”, and instead of saying “two chickens” or “three firs” saying “some chicken” or “some fir”, referring to meat or wood. A good example of this in a slightly different context is (1a). (1b) is perfectly grammatical but looks like an example sentence and I doubt if it’s attested anywhere.
Do you think this is what the makers of Grindr had in mind when they named their app? A universal grindr would alert you to nearby things which you’d normally describe with a count noun that also has a mass reading.
It would be particularly good at Horse.
