Demai (original) (raw)

Demai (Mishnaic Hebrew: דמאי) is a Halakhic term meaning "doubtful". The demai status applies to agricultural produce acquired from common people (am ha'aretz) who are suspected of not correctly separating tithes according to Jewish law. As a result, one who acquires demai produce must separate some of the tithes himself, in case this was not done earlier.
