vektörlerdir

Vektörlerdir is a Turkish predicative form that means "they are vectors." It is formed from the noun vektör (vector) plus the plural suffix -ler and the copula -dir. The overall construction identifies a subject as belonging to the class of vectors and is used in formal or encyclopedic language.

Morphology and grammar: The noun vektör takes the plural suffix -ler, yielding vektörler. The ending -dir functions as a declarative copula, signaling assertion or classification. In Turkish, this copula attaches directly to the noun phrase and does not require a separate verb conjugation for person in present-tense predication. The phrase thus conveys a neutral, definitional statement.

Usage: Vektörlerdir typically appears in contexts such as definitions, explanations, or classifications. It can stand as a complete sentence or follow a demonstrative or subject phrase within a larger sentence. Examples include: "Bu ifadeler vektörlerdir." (These expressions are vectors.) and "Bu iki büyüklük, vektörlerdir." (These two quantities are vectors.)

Notes: The term is not a specialized token beyond standard Turkish grammar; it simply applies the plural form of vektör to a predicative copula. The English translation is straightforward: "they are vectors." See also vektör (vector) and Turkish copula forms such as -dir.
