Inlinguistics, thepegative case (abbreviatedPEG) is a hypotheticalgrammatical case that prototypically marks theagent of an action of giving.
The case has been posited by Danish linguistSøren Wichmann for the Azoyú variety of theTlapanec language, which seems to be the onlynatural language to use such a case. Wichmann writes that he has:
... based 'Pegative' on the Greek πηγή, which means 'origin, source, emanation, etc.' to provide a name for a case that proto-typically refers to a giver as opposed to a recipient.[1]
However, the posited Tlapanec case system is verbal, and it is controversial whetherverbal case as such actually exists.
