start UI-applicative metalinguistic UI-parenthetical
Presently (without this word), there is no "official" way to apply a UI cmavo to another (instead, they merely express simultaneous emotions pertaining to the relevant construct). This word begins a parenthetical which can contain UI cmavo and applies these cmavo as a string of UI to the immediately previous UI cmavo metalinguistically (as if the external UI are any other type of word which can be acted upon by UI). An omitted UI (external or internal) in this case is equivalent to ge'e. Since the produced parenthetical functions as UI, nested or subsequent such parentheticals operate on it as it operates on external UI cmavo. See also: toi'o.
