Köprüsüdür

Köprüsüdür is a Turkish predicative form used to identify or classify a subject as a bridge. It is formed by combining the noun köprü (bridge) with the third-person possessive suffix -sü to produce köprüsü, and then adding the copular suffix -dür, which is the third-person singular form of olmak (to be). The result, köprüsüdür, functions as a complete predicate meaning “is a bridge” or “is the bridge,” depending on context.

The construction illustrates Turkish morphology, where nouns can be extended with possessive suffixes and then linked to a copula to form a nominal sentence. Because Turkish is highly agglutinative, variants can arise with different possessive forms or copular suffixes in related constructions, but köprüsüdür specifically marks a predicative identification using the third-person singular copula.

Usage typically appears in didactic, descriptive, or classificatory sentences, or in short answers within dialogue. It is suitable for illustrating how possession and predication combine in Turkish to make a concise statement about identity or designation. In everyday speech, the form may appear in more extended sentences when the surrounding context specifies the subject and its relationship to the predicate.

Example: In a question-and-answer exchange, one might hear or write: Bu nedir? Köprüsüdür. Translation: “What is this? It is a bridge.” This demonstrates köprüsüdür as a compact predicative form.
