I used to think plural meant 2+, but what about "0.5 hours"?
Is it more accurate to say "0.5 hour"? I don't think that's right, so my definition of "plural" must be inaccurate.
Even "0 days" seems more accurate than "0 day".
Google's definition shows denoting more than one, or more than two. That seems clearly inaccurate.
Does plural mean any amount other than exactly 1? Or what is a more accurate definition?
