pro-sumti and sumyzmico: discourse-interior default it (terbri-specific)
Explicitly and emphatically references the specified default value of the relevant terbri as specified/designated by the discourse; thus, its value is context-dependent and subject to specification modifications. It does not necessarily reference the value defined "officially". (zo'e, implicit or explicit, may do so as well, but the use of this word implies some degree of a more deliberate choice to follow the default specification.) When a default of the terbri is not specified by the previous discourse (nor by the discourse-exterior "official" definition of the terbri if not specification modifications have been made previously), this word is equivalent to completely general and elliptical zo'e. See also: di'oi, di'ei.
