Jos is an abbreviated form of Joshua, which has Hebrew origins and means "God is salvation." This name was popular among several figures in the Old Testament, notably Moses' successor who led the Israelites into the Promised Land after Moses' death. In modern times, Jos gained popularity as a standalone given name rather than just an abbreviation for Joshua. It is often associated with strength and leadership due to its biblical roots but has since evolved to stand alone as a unique and distinctive name choice.
"The name Jos has seen a resurgence in popularity from the late 20th century onwards, with a noticeable increase in usage between 2005 and 2019."
