        Word: kei'ai [jbovlaste]
        Type: experimental cmavo (YOU RISK BEING MISUNDERSTOOD IF YOU USE THIS WORD)
  Gloss Word: difference set in the sense of "mekso; generalized"
  Gloss Word: image under f in the sense of "image of a function on a set"
  Gloss Word: set of results of operator in the sense of "mekso"
  Gloss Word: sum set in the sense of "mekso; generalized"
     selma'o: PEhO
  Definition: mekso style converter: elementwise application of operator
       Notes: Prefixed to an operator/function that operates on numbers,
       thereby transforming it into a set operator (thus its arguments
       must be sets where before they were numbers), as defined in a
       given structure; the result is a function of the same arity.
       Produces the set of all numbers that are given by some ordered
       tuple of elements (the nth term of which belongs to the nth set
       specified, for all n) with the operator acting on them/the
       tuple (per the rules of that operator). The set produced may
       include empty terms and/or infinity. Let "@" represent the
       operator and "$x_i$" represent a set for all i; then x1 kei'ai
       @ x2 boi x3 boi x4 boi $\dots$ = Set(@$(t_1, t_2, t_3, t_4,
       \dots)$: $t_i$ in $x_i$ for all i); the ordered Cartesian
       product of the operands of 'kei'ai @' must be a subset of the
       domain set of '@'. If f is unitary and we convert it to a set
       operator 'kei'ai f' = F, then for any good set A, $F(A) =
       \operatornameimg_f (A)$, which is the image of A under the
       function/map f.  See also kei'au for a similar but different
       word.
