kimdir

Kimdir is a Turkish word-form used to ask about someone's identity. It is a fusion of the interrogative pronoun kim (who) and the copular suffix -dir, which marks a predicative identity in Turkish. The combination yields a single-word question meaning "Who is he/she?" or "Who is this?" depending on the context.

Usage: Kimdir appears in direct questions about identity. It is commonly used in biographical headlines or introductory sentences such as "Bu kimdir?" (Who is this person?) or "O kimdir?" (Who is he/she?). The suffix -dir belongs to a category of copula endings in Turkish that attach to pronouns or nouns to state or inquire about identity; there are several allomorphs (-dır, -dir, -dur, -dür) that harmonize with the preceding vowel.

Notes: Although primarily a question form, kimdir is part of Turkish grammar rather than a stand-alone lexical item. It can appear in both written and spoken Turkish, often with a formal or informational tone. Its use is typical in encyclopedia-like introductions, biographies, or news reports when identifying a person.
