Casmir

Casmir is a masculine name representing a variant spelling of Casimir, which has Polish and Slavic origins. Derived from the elements 'kazi' meaning 'destroyer' and 'mir' meaning 'peace' or 'world,' it paradoxically translates to 'destroyer of peace' or 'announces peace.' The name has royal historical connections, borne by several Polish kings and saints including Saint Casimir, patron saint of Poland and Lithuania. While less common than the traditional spelling Casimir, the streamlined version Casmir maintains the name's strong, dignified character while appearing slightly more modern. The name has modest usage in Poland, Eastern Europe, and among Polish diaspora communities, appealing to parents seeking names with Slavic heritage and historical depth.

Casmir is also given to girls.

Pronounced KAZ-mir.
