a way to say “the other” as opposed to “another” would be useful. Perhaps if there’s a way to say “only” in the sense of “the only, unique”, that might help.
Possibly something with Dopbe opposite,
antithetical, contradictory.
Oh, that’s a good idea. And I realized that the ambiguity of “latlh” is almost certainly intentional, just as “vay'” is ambiguous in whether it refers to a definite or indefinite someone or something.
