bunun

Bunun is a Turkish pronoun and determiner formed from the demonstrative bu (“this”) combined with a genitive/possessive suffix. It functions to indicate a relationship between the thing being referred to and the rest of the sentence, roughly translating as “of this” or “this one’s” in English. In ordinary discourse, bunun introduces or references information about a thing mentioned earlier or assumed known.

Formation and usage notes: The form bunun is produced by attaching the genitive/possessive suffix to the demonstrative bu. It appears in a range of constructions to express possession, relation, or attribution with respect to “this.” Common phrases include bunun için (for this/for that purpose), bununla (with this), and bunun nedeni (the reason for this/this one). As a result, bunun frequently serves as the head of a noun phrase or as part of a prepositional phrase.

Examples: Bunun nedeni nedir? (What is the reason for this?) Bunun için yeni bir plan ürettik. (We devised a new plan for this/for that purpose.) Bununla ilgili ayrıntılar şu anda yok. (There are no details about this matter at the moment.)

Relationship to other forms: Bunun is the genitive form associated with bu. Turkish also uses related forms with other demonstratives, such as şunun, onun, and their corresponding compound forms (e.g., bununla, şununla), to express similar relations for different reference points.
