su'ero PA*4 cmavo-compound

digit/number: any number

"Not more than all"; idiom to indicate that any number (within contextual limits, i.e. rone'e bi'i ro) would satisfy the predicate. su'ono "at least zero" is also usable in contexts where negative numbers aren't meaningful (e.g. most quantifiers). See xe'e, xo'e

In notes:

digit/number: any/non-specific referent; modifies quantifier to indicate that it is not important what the specific members of the referential set are
