bilgisini

Bilgisini is a Turkish grammatical form that functions as the accusative object meaning “his/her knowledge” or “the information of someone.” It is built from the noun bilgi (knowledge, information) plus the third-person possessive suffix si, and the definite accusative suffix ni. When combined, the result is bil gisini, a definite direct object referring to the owner indicated by the possessive.

In Turkish, possessive suffixes attach to the noun to show ownership, and the following accusative suffix marks the noun as a definite direct object. The form bil gisini thus specifies that the possessed knowledge belongs to a third person and is the object of the verb. The same construction can be adapted for other persons by choosing the corresponding possessive forms, yielding phrases such as bilgim (my knowledge) or bilgin (your knowledge) with their own accusative forms where used.

Usage and nuance: bil gisini appears in sentences where someone’s information or knowledge is the object of an action, such as sharing, storing, or evaluating that knowledge. It is common in formal or written Turkish, including discussions of privacy, data handling, or intellectual property, where ownership of information matters.

Example sentences:

- Onun bilgisini paylaştı. (He/She shared his/her information.)

- Kullanıcının bilgisini korumak için önlemler alındı. (Measures were taken to protect the user’s information.)

- O, bilgisini gizledi. (He/She hid his/her knowledge.)

Notes: Turkish grammar allows many possessive and case forms of bilgi; bil gisini specifically highlights a third-person possessive object in the accusative.
