I noticed today that ENOUGHS is valid in Scrabble(tm), and I realize "enough" can be used as a noun ("I've had enough!"), but I'm unaware of any context where one might use its plural. Perhaps it's used in some setting I'm not aware of?
The only use of enoughs that I could find is in this book. Even here, it is used within quotation marks to show its unusual usage.
Lerner thinks that this won't work; the connections are too tenuous as all the "enoughs" show.
The Corpus of Contemporary American English cites 5 instances of enoughs being used. Apart from errors like "Enoughs enough", it has a couple that might work:
Good enoughs, 40%. Divorce caused tumult but didn't make lasting impression, good or bad... -- USA Today (Presumably, this is in explanation to some kind of graph or study.)
...if you were nimble enough and canny enough and stubborn enough and enough other enoughs...
Make of that what you will. I'm not sure if this kind of usage qualifies the word's acceptance in Scrabble.
Definition of enough (noun) form
adequate amount; sufficient degree
I decided to consult Google and found "close enoughs" and "just enoughs."
These could be used as "There have been too many close enoughs already!"
However, the same phrase more properly written would be "There have been too many 'close enough's already!"
I cannot think of a time where enoughs would be used alone so this is a meager answer at best.
