Iustus

Iustus is a Latin masculine name derived from the adjective iustus, meaning just or righteous, itself rooted in ius, the Latin word for law or right. It was commonly used in the early Christian world, and several saints bore the name, including a martyred child venerated in Spain and an early Bishop of Canterbury. The name passed into various European languages, giving rise to forms such as Justus, Justin, and the feminine Justa.
