Tretya

Tretya is a transliteration of Cyrillic spellings trétya or тре́тья, meaning "the third" in the feminine form. In Russian, тре́тья (tretya) is the feminine form of the ordinal numeral третий (tretiy). In Ukrainian, третя (tretia) is similarly the feminine form. The word is used to modify feminine nouns and agrees in gender, number, and case.

Etymology and form: The term derives from Proto-Slavic *tretiъ, from the root for "three." In each language, the spelling and pronunciation reflect language-specific phonology, with tréтья in Russian and третя in Ukrainian commonly transliterated as tretya in English.

Usage and variations: As an ordinal adjective, tretya appears in references where the noun is feminine, such as "the third day" or "the third chapter" when the noun is feminine (Russian: третий день vs. тре́тья страница; Ukrainian: третій день vs. третя сторінка). The form changes to agree with the noun’s gender, number, and case, and it may have different stressed variants across dialects.

Toponymy and related forms: In some Slavic-speaking regions, Tretya or similar forms may appear in place names or surnames derived from the adjective. This article focuses on the linguistic term rather than any particular place or organization.
