Attested in English since the late 1930s, from Yiddish קישקע (kishke), from Slavic—Polish kiszka, Russian кишка́ (kišká), or Ukrainian ки́шка (kýška). Ultimately from Proto-Slavic *kyšьka (“intestine, stomach”). May be related to Sanskrit कोष्ठ (koṣṭha, “intestine”) or Ancient Greek κύστις (kústis, “bladder”).
