türlerdir

türlerdir is a Turkish predicate form meaning “they are types” or “they are kinds.” It is built from the plural noun türler, meaning “types” or “kinds,” plus the copular suffix -dir, which functions as the present tense assertion “are” in Turkish. The construction is used to identify or classify a set of items as belonging to particular categories.

In Turkish, the copula -dir has several phonological variants (such as -dır, -dir, -dur, -dür) that harmonize with the preceding sounds. The written form türlerdir represents the standard combination of a plural noun with the copula, and the suffix does not reflect subject person in the same way as verbs do; it simply marks the assertion that the subject constitutes a certain category.

Usage and register: türlerdir is common in formal, academic, or technical Turkish, including scientific writing, taxonomy, and analytical descriptions. In everyday speech, speakers often omit the explicit copula or use alternative constructions. The form emphasizes classification and certainty about the categorization being stated.

Related notes: tür means “type,” “kind,” or “species,” and ler is the plural suffix. The phrase türlerdir serves as a concise way to assert that a given set of elements belongs to specified categories, especially in statements that aim to define or compare groups. Example: Bu gruplar farklı türlerdir. (These groups are different types.)
