Creates a predicate abstraction sumti out of a full bridi clause, binding all the necessary lambda variables to the ko'a-ko'u pronoun series. The number of bound variables must be indicated by appending {xi} followed by that number to the word {fo'ai}, unless only one variable (namely {fo'a}) is bound, in which case the {xi} marking is optional.
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.
incidental/non-restrictive adverbial: converts selbri to bridi adverbial term. The first place of the converted selbri is claimed to be such that the outer bridi satisfies it, and the outer bridi is claimed. {broda noi'a brode} means {lo nu broda ku goi ko'a cu fasnu .i ko'a brode}.
hybrid {be} and {bei}: sumti link to attached sumti to a selbri, repeatable, valid for both first and subsequent attachments.
Can also appear immediately after gadri like {lo}.
