Hospodar or gospodar is a term of Slavonic origin, meaning "lord" or "master".
Gospodar (Belarusian: гаспадар, Bulgarian: господар, Macedonian: господар, Serbian: господар, Ukrainian: господар ) is a derivative of gospod, lord, (spelled with a capital G, Gospod, it means Lord, God).
The pronunciation as hospodar of a word written as господар in many Slavonic languages which retain the Cyrillic script could be due to the influence of whether Ukrainian, where the first letter is pronounced as [ɦ] or that of Church Slavonic where it is pronounced as [ɣ].
In Ukrainian, hospodar is usually applied to the master/owner of a house or other properties and also the head of a family. The hospodar's house is called as hospóda . There also an alternative form for the head of the household - gazda which also common in Hungary. Hospod is used exclusively when referring to the Lord and has only has a slight relation to hospodar.
The title was used briefly towards the end of the Second Bulgarian Empire. In 1394-95, Ivan Shishman of Bulgaria referred to himself not as a Tsar (as traditionally), but as a gospodin of Tarnovo, and in foreign sources was styled herzog or merely called an "infidel bey". This was possibly to indicate vassalage to Bayezid I or the yielding of the imperial title to Ivan Sratsimir.
