komplekslerdir

Komplekslerdir is a Turkish phrase consisting of the plural noun kompleksler (complexes) followed by the copular suffix dir, functioning as the third-person plural form of “to be” in a present-tense declarative sentence. The combination translates roughly to “they are complexes” or “these are complexes.” The form is used to classify or identify multiple items as complex entities within a statement.

Etymology and morphology: The base noun kompleks means a complex in various senses, such as a psychological complex, a building complex, or a mathematical/abstract complex, depending on context. The plural suffix -ler attaches to kompleks to form kompleksler. The copula dir is one of several allomorphic forms of the Turkish copula “to be” and appears in formal or written Turkish to mark assertion. Its exact spelling can vary (dır, di̇r, dur, dür) to reflect vowel harmony and the preceding sound, but in the canonical orthography it is written as dir.

Usage: Komplekslerdir is typically used in formal or written Turkish to define or categorize a subject as being a complex. In everyday speech, Turkish often omits the copula, so the same idea can be conveyed with kompleksler or with different constructions, depending on context. For example, Bu kavramlar komplekslerdir means “These concepts are complexes.” The term may appear in discussions of linguistics, psychology, architecture, or other fields where the notion of a “complex” is relevant.
