kombinasyonudur

Kombinasyonudur is a Turkish grammatical form meaning “is a combination.” It is created from the noun kombinasyon (combination) plus the copular suffix -dur, which marks the third person singular declarative of the verb olmak (to be). In Turkish, this suffix is used to form predicate nominal clauses, for example in sentences that define or classify something.

Etymology and morphology: The base word kombinasyon is a loanword borrowed from French combinationi/combination, adapted into Turkish as kombinasyon. The suffix -dur (with its allomorphs -dır, -dir, -dur, -dür depending on vowel harmony) attaches to the stem to produce a definitional or classificatory statement. The resulting form, kombinasyonudur, literally means “it is a combination.”

Usage: Kombinasyonudur is most common in formal, expository, or definitional Turkish, such as dictionaries, textbooks, scientific writing, or analytic discourse. It serves to assert identity or classification of a subject as a combination. Typical constructions include Bu, bir kombinasyondur. (This is a combination.) or Bu durum, bir kombinasyondur. (This situation is a combination.)

Examples:

- Bu iki parçanın birleşimidir, fakat bu ifade bir kombinasyonudur. (This is the combination of two parts; this expression is a combination.)

- Bu formül, bir kombinasyondur. (This formula is a combination.)

Notes: In everyday language, speakers may prefer simpler predicates such as Bu bir kombinasyondur or Bu bir kombinasyonudur uplifted in formal contexts. The form highlights definitional or classificatory statements and is less common outside formal Turkish usage.
