kütlesidir

Kütlesidir is a Turkish predicative form built from the noun kütle, meaning mass or bulk, with the third-person possessive suffix -si and the copular suffix -dir. The combination yields a formal expression that can function as a complete predicate, roughly translating to “is the mass (of)” in English when used in a sentence. It is primarily encountered in formal, definitional, or scientific contexts.

Morphology and construction: The base word kütle takes the possessive suffix -si to indicate ownership or association, forming kütlesi (its mass). The copular suffix -dir is then added to create a predicative form, resulting in kütlesidir. Turkish vowel harmony governs the suffix forms, and -dir carries a present, assertive, or identifying force, often used for emphasis or formal declaration. The exact meaning depends on the surrounding possessive noun phrase and the overall sentence structure.

Usage and examples: In formal Turkish, kütlesidir can introduce a definition or identification. For example: Bu cismin kütlesidir. This sentence identifies what the object’s mass is, roughly “It is the mass of this object.” In everyday language, speakers would more likely use a different construction, such as Bu cismin kütlesi 5 kilogramdır or Bu cismin kütlesi beş kilogramdır, to state a specific mass. The form kütlesidir is thus a stylistically marked option for explicit identification of mass in precise discourse.
