Where did this word come from?
Biblical root כ.ש.ר "be fit, proper, succeed" (Esther 8:5, "ve-hadavar kasher," "and the thing is proper"). Rabbinic Hebrew made it the master adjective of dietary law (kasher l'mehadrin, glatt kosher, "glatt" is Yiddish for "smooth," i.e., the lungs). Yiddish carried kosher into English (attested 1860s+); modern Hebrew uses it universally for legitimacy.
