ölçüsüdür

ölçüsüdür is a Turkish finite verb form derived from the noun ölçü, meaning measure or standard. It functions as a predicative form that states “is the measure” or “is the standard,” and it is used to identify or define a subject as a specific measure within a context. The form is typically encountered in formal or technical language, including mathematical or evaluative discussions, rather than everyday casual speech.

Morphology and formation

The word is built from ölçü plus the third-person possessive suffix -sü, yielding ölçüsü (“its measure”), followed by the copular suffix -dür, which marks the third-person singular present tense “is.” The resulting combination, ölçüsüdür, thus literally means “it is its measure” and can be used to equate a subject with a particular standard or criterion. This pattern demonstrates Turkish agglutination, where multiple suffixes attach to a base word to convey possession and predication in a single word.

Usage and examples

ölçüsüdür appears in sentences that define or specify a standard, benchmark, or criterion. Examples:

- Bu değer, grafiğin en yüksek değerinin ölçüsüdür. (This value is the measure of the graph’s highest value.)

- Bu gösterge, performansın ölçüsüdür. (This indicator is the measure of performance.)

In context, ölçüsüdür is a formal way to pronounce a defining relationship, often found in written explanations, reports, or analytical prose.

Relation to Turkish grammar

ölçüsüdür illustrates how Turkish combines a noun with possession and a copula to create a complete predicative clause. It complements related forms such as ölçüdür, which can occur with different subjects to express equivalence to a measure or standard.
