Darek is a Polish masculine given name, functioning as a diminutive of Dariusz. The name Dariusz itself is the Polish form of Darius, which traces back through Latin and Greek to the Old Persian name Darayauš, ultimately from Darayavauš, meaning "possessing goodness"—from daraya (to possess, hold) and vahu (good). Three ancient kings of Persia bore the name Darius, most notably Darius the Great, who expanded the Achaemenid Empire and launched invasions of Greece, including the famed Battle of Marathon. Linguistic and Cultural Context In Polish, Darek is formed by clipping Dariusz and adding the diminutive suffix -ek, a common pattern in Polish name formation (e.g., Marek from Mariusz, Jarek from Jarosław). The name is pronounced [ˈda.rɛk] and is a familiar, informal short form used among family and friends. Since 2000, Darek has consistently been given to about 30–60 newborn boys annually in Poland, reflecting its status as a well-known but not wildly popular diminutive. Its usage as an independent given name has declined somewhat as formal names have trended back toward full forms, yet it remains in moderate circulation. While in English-speaking contexts "Darek" also appears as a variant spelling of Derek (of Germanic origin), the Polish name is distinct both etymologically and phonetically, linked to Persian royal heritage rather than Germanic root. Related Forms Darek shares roots with various European forms of Darius, including Italian Dario, Croatian Darijo, Lithuanian Darijus, and Romanian Darius. Biblical forms include Daryawesh in Hebrew.
