pro-sumti: the universal argument/value; syntactically-contextually and type-permitted maximally generic in its typing
It is a pro-sumti with a universal reference set (restricted to syntactically-demanded/appropriate type). Probably semantically maximally and generally elliptical/generic. Typing can be restricted by (possibly metalinguistic) restriction. See also: zai'o (pro-sumti; empty), gai'o (pro-bridi; empty), cei'i (pro-bridi; universal), ctaipe.
