I know most of you don’t give a damn about the use of “less” for countable nouns, as it is indeed a very old practice and is dominant in real world English. Brave descriptivists, I salute you!
So this question is addressed to the other sector of humanity, those that scrupulously say “less milk” but “fewer apples”. I know you’re out there.
What would you say in a case where the noun is plural in form but bulk in logical nature?
I’m thinking particularly of “emissions”, a big topic these days.
Surprisingly (for me at least), “fewer emissions” wins the googlefight but a narrow margin.
“fewer emissions” 64,100 googlits
“less emissions” 50,900 googlits
