te'au
experimental cmavo iterated Cartesian product with self: A × A × ... × A, n times. Probably belongs to selma'o VUhU but, since it is iterated JOI, there is the case for that. First argument A is a set or similar object; second argument n is a nonnegative integer; the result is the crossproduct of A with itself n times. Used as a shortcut for longer, arguably more preferable, constructions so that one can more closely say "R three" and mean R^3. Emphatically not equivalent to exponentiation; it only works on sets and similar objects. See also: te'a, pi'u, se'au.


se'u'o
experimental cmavo selbri conversion question Asks for the SE word that is intended (or at least makes the sentence true). Subscript a set of numbers that represent the order of terbri in question; the subscripted set can be a set of ordered or unordered tuples, specifying exactly which terbri may be exchanged. 'la .ralf. se'u'o xi li re ce li ci pi'u li re cebo li ci klama by boi cy' = 'Did Ralph come to B from C or to C from B?' (notably, 'Did B come to Ralph from C?' is not a possible option for answering the question). An answer is a SE string that is allowed by the selbri and by the subscripts; continuing the example, if the response is 'Ralph went to C from B', one would respond with '.i setese'. Any SE word works for the general question possibility (which is the unrestricted/nonsubscripted case). Essentially 'se'u'o xi sy' is equivalent to 'se xi li xo poi ke'a cmima sy' (where 'te' is basically understood as ' se xi li jo'i pa boi ci te'u ', etc.), but the answer can be a complicated ordered sequence/string of SE words; this word complements specifically fi'a in the typical/same way that SE complements FA. Typically, leaving the subscripted set vague or not completely free of every possible semantic or syntactic pathology is perfectly fine; syntax and practicality will typically restrict it enough for reasonable responses to be made. See also: re'au'e (which alone would be used in answering that 'Ralph goes to B from C' in the previous question).
