Sanskrit

From Proto-Indo-European *(s)kewh₂- (“to poke, cut into, tear”), related to Hittite iskunant- (“spotted”) and Hittite iskunahhis (“marked”, 3sg.past), Lithuanian kiáuras (“perforated”), and maybe Proto-Germanic *hūdiz, Latin cutis (“skin”), Lithuanian kiáutas (“shell, rind, peel”) via the connection 'flaying' < 'tearing' (just as Ancient Greek δέρμα (dérma, “skin”) is from δέρω (dérō, “to flay”)).
