Number suffix initiating a subordinate clause representing a predicate whose arity is the suffixed number; the lambda variables representing the predicate slots are bound from the ko'a-ko'u series in their dictionary ordering; the number of bound variables is the same as the predicate arity.

For example, if the selected arity is two (re ky'oi), then only ko'a and ko'e are bound, and ko'i etc. are not bound. Terminator: ku'au.
