pentacle

Etymology

PIE word *pénkʷe From Middle French pentacle, from Old French pentacol (“pendant”), from pent (“hangs”), a (“from”), and col (“neck”), thus "hangs from neck". Likely reanalyzed in medieval times as coming from penta- (“five”) and -culum (object forming suffix), as evidenced by the Latinized form pentaculum and the narrowing of the modern sense to a five-pointed design, especially a pentagram.
