Jarek is a Slavic male given name, commonly used as a diminutive of names beginning with the Slavic element jarŭ meaning "fierce, energetic," such as Jarosław or Jaroslav. Though originally a diminutive, Jarek is often used as an independent given name in Poland and the Czech Republic. Etymology The core element jarŭ is an ancient Slavic root signifying vigor and intensity. The longer forms Jarosław and Jaroslav combine this root with slava ("glory"), yielding the meaning "fierce and glorious." This structure is reflected in the Yaroslav root, borne by Yaroslav the Wise, the 11th-century grand prince of Kyiv. Related diminutives include the Czech Jára and the Polish Slávek. Feminine forms such as Jarosława and Jaroslava parallel the masculine. Notable Bearers Figures named Jarek span sports, arts, and activism. In sports, Jarek Broussard is an American football player, Jarek Dymek (born 1971) a Polish strongman, and Jarek Srnensky (born 1963) a Swiss tennis player. Musicians include Jarek Hardy (Canadian) and Jarek Śmietana (1951–2013, Polish jazz). The name also appears in fiction, notably as a character in the Mortal Kombat franchise.
