güçlüdür
Güçlüdür is a Turkish predicative form meaning “is strong.” It expresses a definite attribute of a subject and uses the adjective güçlü (strong) together with the third-person singular present copula -dür, one of the -dır/-dir/-dür/-dur allomorphs selected according to Turkish vowel harmony. The form marks a factual, declarative statement in standard Turkish, often found in formal writing and signs.
In usage, güçlüdür works as a simple predicate: the subject before the verb carries the attribute of
- Bu köpek güçlüdür. (This dog is strong.)
