digit/number: strictly greater (more) than 0 but strictly less than all (jbo.: "ro").
Equivalent to the word "some" in "at least some (of) kids are cute" (this would be translated with "su'o su'o'o"; "some" here on its own means "at least 1 but not all" and the "at least" modifies it to be "at least 1 but not necessarily all").
