Origins

From Proto-Italic *kastrāō, denominative in -ō perhaps from a lost instrumental noun, Proto-Italic *kastrom (“knife”), from Proto-Indo-European *ḱstróm (“cutting tool, knife”), from Proto-Indo-European *ḱes- (“to cut up, to slaughter”); compare Sanskrit शस्त्र (śastra, “sword, dagger”). See also castrum, careō.
