vechnyy

Vechnyy is the transliteration of the Russian adjective вечный, meaning eternal, perpetual, or everlasting. It is used to describe something without end in time or something timeless in quality. The noun form вечность denotes eternity, from which the adjective is derived. Cognates appear in other Slavic languages, for example Ukrainian vichnyy (вічний) and Polish wieczny.

In Russian grammar, вечный has the usual adjective inflections: masculine вечный, feminine вечная, neuter вечное, plural вечные. The adverbial form is вечно, meaning forever or eternally. The word is frequently used in theological, philosophical, literary, and everyday contexts.

Usage notes include a distinction from similar terms such as постоянный (constant, stable over time) and непрерывный (continuous, without interruption). Vechnyy emphasizes an end or limit that is not reached, rather than mere repetition or regularity. It often carries a sense of moral or metaphysical permanence in addition to temporal eternity.

Common collocations and phrases include вечная истина (eternal truth), вечная жизнь (eternal life), вечная память (eternal memory), вечные ценности (eternal values), and вечный огонь (eternal flame). In scientific or humorous contexts, it can appear in juxtaposition with notionally perpetual concepts, such as вечный двигатель, though such usage is typically idiomatic or metaphorical rather than literal.

See also: вечность, вечная память, вечная жизнь; related terms in other languages include eternal (English), éternel (French), ewig (German).
