birimdir

birimdir is a Turkish word formed by the noun birim, meaning unit or division, together with the copular suffix dir. The combination yields a declarative predication, literally translating to “it is a unit.” In Turkish, the copula suffixes -dir, -dır, -dur, -dür reflect vowel harmony and are used to make an explicit assertion about the subject. The form birimdir occurs when the stem ends with a vowel that harmonizes with the i-vowel in the suffix.

Usage and meaning: birimdir is used to classify or identify something as belonging to the category of a unit, division, department, or similar unit of measure or organization. It is commonly found in formal, descriptive, or written Turkish, such as manuals, catalogs, or organizational documents. In casual speech, speakers often omit the copula and say simply Bu birim or O birim to convey the same idea.

Examples:

- Bu birimdir. (This is a unit.)

- O birimdir. (That is a unit.)

- Bu bölüm birimdir. (This section is a unit/department.)

Notes: The word birim covers senses related to a unit of measurement, a structural unit, or a organizational unit, depending on context. The -dir copula emphasizes classification and identity; alternatives with other copula forms (-dır, -dur, -dür) are used according to vowel harmony rules in Turkish.
