x_{1} (predicate) is true when applied to argument list x_{2} (sequence)

Synonymous to zilbri. The x1 slot can be filled with a property/relation (ka) whose number of free slots match the length of the sequence x2. It can also be filled with a bridi abstraction (du'u) —nullary predicate—, in which case the x2 should be the empty set or possibly zi'o. See also bridi.
