The name 'Orohost' belongs to the personal name of the Pereiaslav boyar and voivode Volodymyr Vsevolodovych from the year 1600. This name is part of the Proto-Slavic two-component masculine names. The postpositional component is likely the word "host", which means 'foreigner' or 'merchant', modified under the influence of the ancient possessive suffix *-jb. The prepositional part of the name is not transparent, although phonetically it resembles the name of the Slavic deity from the 6th century, Ardagost.
