birimlerdir

Birimlerdir is a Turkish phrase meaning "they are units." It is formed from birim (unit) plus the plural suffix -ler to make birimler (units), followed by the copular suffix -dir, which marks identity or classification in Turkish. The whole word birimlerdir functions as a predicate meaning "they are units." This construction is common in formal or written Turkish, particularly in definitions, explanations, or labels, where the speaker wants to make a definite statement about what a group or category is.

Grammar and usage: Turkish normally uses a copula as an explicit verb for identity; -dir has several allomorphs (-dır, -dir, -dur, -dür) that reflect vowel harmony, and it carries emphasis in formal contexts. In everyday speech, the copula is often omitted. The subject and predicate can appear in different orders, but the copula provides a clear link between them. Example: Bu elemanlar birimlerdir — "These elements are units."

Beyond grammar, birim can refer to a unit in measurement, a component in a system, or a modular section in software or hardware. Therefore birimlerdir may appear in technical Turkish to assert that a set of components are units or modules. The term is widely understood among Turkish speakers and appears in dictionaries and academic texts.
