दाढिका

Sanskrit

A corruption of दंष्ट्रिका (daṃṣṭrikā), a compound of दंष्ट्र (daṃṣṭra, “large tooth, tusk”) +‎ -इक (-ika, possessive suffix) +‎ -आ (-ā, feminine suffix), with a semantic shift from "tooth" to "beard", both of which are within the same general facial area; the first element is from Proto-Indo-Iranian *dánštram, from Proto-Indo-European *denḱ-trom, from *denḱ- (“to bite”) + *-trom (suffix denoting a tool or instrument). Cognate with Avestan 𐬙𐬌𐬲𐬌-𐬛𐬄𐬯𐬙𐬭𐬀 (tiži-dąstra, “having sharp teeth”).
