The name "Stryiets" has an interesting origin related to an ancient Slavic term. It may derive from the word "stry," which means "father's brother," or from "striyets," which is used to denote a "resident of the city of Stryi." In the Ukrainian language, the root "stry" can be complexified with various forms and is realized in surnames such as "Stryiko," "Strychko," and others.The lexeme "Stryiets" is first mentioned in Ukrainian written records in 1409: Lord Stryiets, the voivode of Galicia, from the city of Halych. In the Polish language, the anthroponym "Stryecz" also appears several times in the context of personal names during the 14th and 15th centuries.
