sumti tcita

/suːm.ti.tʃiː.tɑː/

noun

(Lojban grammar) a (Lojban analogue of a) preposition; a "sumti label" for extra sumti (“arguments”) of the selbri which the sumti tcita modifies. (By "extra sumti" are meant sumti which have not been assigned places in the selbri (“predicate”)'s place structure).

I need a sumti tcita for my research.

(Lojban grammar) a (Lojban analogue of a) preposition; a "sumti label" for extra sumti (“arguments”) of the selbri which the sumti tcita modifies. (By "extra sumti" are meant sumti which have not been assigned places in the selbri (“predicate”)'s place structure).

Thus, a safer statement than yours is the claim that a fi'o construction can be devised that is semantically equivalent to any sumti tcita needed which is NOT in the lexeme BAI set.
