Correct plural form of a zero quantified noun
I could have:
- Zero books
- One book
- Two books
Why is zero in plural form?
Edit
Per Merriam-Webster:
Plural (adj): of, relating to, or constituting a class of grammatical forms usually used to denote more than one or in some languages more than two
Singular (adj): of, relating to, or being a word form denoting one person, thing, or instance
So by this logic, our choices are one or more than one. Maybe it's a bug :-)
