Zhelko is a Slavic masculine name, which is a suffixal derivative of the name Zhelimir. This name is composed of the word "zhela," meaning 'desire, aspiration.' The name Zhelko came to Ukrainians from Serbia and Croatia during the interwar period. For instance, in the lists of students from a secondary school in the city of Šid in the 1950s, names such as Zhelko Tirkyailo and Zhelko Faifrich can be found (research by Mudry - Salamon, p. 258).
