x_{1} (ka) is the relation of predicate x_{2} (du'u), which has arguments x_{3} (sequence of sumti).

In Lojban, for example, "lo ka ce'u prami ce'u cu selbri lo du'u mi prami do ku mi ce'o do". In the mathematical notation P(x, y, z) for a predicate, the relation P is the selbri. Note that x_{1} is not textual, even though Lojbanists informally tend to call a word or phrase "the selbri" of an utterance. For this usage see selbrisni.
