c1 (quoted word(s)) is a name of c2 used by c3 that morphologically [strict] is brivla bv1 in language x5
The name must strictly be a (sequence of) brivla (according to rules for language x5); as such, in Lojban, the word(s) c1 must end with vowels and in fact must exactly follow the morphology of brivla. See also: brivlasmicme (a specialization); jvocme (a different specialization that is analogous but restricted to Lojbanic lujvo). Language is specified to be x5 rather than bv_n because the definition for brivla has not yet gained consensus and this particular terbri is dependent thereupon.
