Strictly speaking, {mo} is a *bridi* question and picks up selbri and brivla
as degenerate cases (the most common, perhaps, as often in weird little societies like Lojbnaistan). Thus viewed, {mo mo} don't make no mo' sense, as does not two bridi run together without a connective. That said (look Ma, and ablative absolute!), one might argue that {mo mo} does have a real use in the language, perhaps to indicate how specific and answer is expected -- with three, or even five, levels of specification. But that is strictly an idiom, though a reasonably clear one in the circumstances. |
