Joost

Joost is a Dutch masculine given name derived from the Latin Iustus, meaning just or righteous, itself rooted in the Latin word ius, meaning law or right. It entered Dutch usage as a vernacular form of the Latin name borne by several early Christian saints. The Dutch poet and playwright Joost van den Vondel, often considered the greatest writer in the Dutch language, is among its most celebrated historical bearers. Related forms include Jodocus, Just, and the Latinized Justus.
