Olek

Olek is a Polish masculine given name functioning as a diminutive of Aleksander, the Polish form of Alexander, which derives from the ancient Greek name Alexandros, composed of the elements alexein, meaning to defend, and aner, meaning man. It shares its ultimate roots with a wide family of European forms including Aleksander, Aleksandr, and Sasha. The name Alexander itself was famously borne by Alexander the Great, the Macedonian king whose conquests spread Greek culture across much of the ancient world, giving the name enduring popularity throughout Europe and beyond. Olek remains in common affectionate and informal use in Poland today.
