bilir

Bilir is the third-person singular present tense form of the Turkish verb bilmek, meaning "to know." It is used to indicate that a subject knows something and can appear with or without an explicit subject: O bilir means "he/she knows." The form is built from the root bil- plus the present tense suffix -ir. Related forms include bilirim ("I know"), bilirsin ("you know"), and biliriz ("we know"). The negative is bilmez ("does not know"), and the question form is bilir misin? ("do you know?") or bilir misiniz? (formal or plural).

Bilir is also a Turkish surname. It occurs among Turkish-speaking populations and can be found in various contexts, including contemporary names in media, academia, and sports. As a surname it is capitalized Bilir.

Pronunciation is approximately bi-lir, with the primary stress on the second syllable. The spelling reflects Turkish phonology and vowel harmony: the root bil- and the suffix -ir.

Related linguistic terms include bilgi ("knowledge"), bilgilendirmek ("to inform"), and bilinç ("consciousness"), all tied to the same bil- root.
