Yetkisine

Yetkisine is a Turkish term formed from yetki (authority, jurisdiction) with the third-person possessive suffix -si and the dative suffix -e, yielding yetkisi and then yetkisine. The literal meaning is “to his/her/its authority,” and the phrase is used to indicate that something falls within a particular entity’s power, competence, or jurisdiction.

In usage, yetkisine is common in legal, administrative, and organizational language. It helps locate the scope of authority and answers questions such as whose authority applies or under whose jurisdiction a matter lies. Turkish sentences often pair this form with verbs and phrases like ait olmak (to belong to) or girmek (to fall within): for example, Bu karar savcının yetkisine aittir (This decision belongs to the prosecutor’s authority). Another example is Bu konu belediyenin yetkisine girer (This issue falls under the municipality’s jurisdiction). The expression can also be used in more general phrases such as yetkisine bağlı olmak (to be under someone’s authority).

Morphologically, yetkisine is a combination that demonstrates Turkish possessive and case endings in action, and it is typically part of a larger predicate rather than a stand-alone noun. It is primarily a formal, administrative, or legal construction, conveying the idea of delegated competence rather than informal influence. Related concepts include yetki (authority), yetkili (authorized person), and phrases like yetkisine aittir (belongs to one’s authority).
