This distinction was first tentatively suggested by the grammarian Robert Baker in 1770, and it was eventually presented as a rule by many grammarians since then. However, modern linguistics has shown that idiomatic past and current usage consists of the word less with both countable nouns and uncountable nouns so that the traditional rule for the use of the word fewer stands, but not the traditional rule for the use of the word less.
I was just stirring the pot, and I love this response
Yeah but the summary could be lesser words.
I love that there’s a wikipedia page on this.
I hate that doing the wrong thing consistently automatically makes it the right thing.
Use “less” for countable nouns and “fewer” for uncountable nouns as a little language prank.
Eh. I could care fewer.
Couldn’t* care fewer. Get it right.
I couldn’t’ve’d cared fewer than I amming.
