korisnikom

Korisnikom is the instrumental singular form of the noun korisnik, used in Croatian, Bosnian and Serbian. The base word korisnik means “user” or “person who uses” a device, service, or system. The noun is formed from the root related to use or benefit, with the agentive suffix -nik, and takes the instrumental ending -om in this form.

In grammar, korisnikom functions as the instrumental case and is commonly seen after prepositions that require the instrumental, such as sa or s (with). It denotes the instrument, the partner in an action, or the entity with which something is done. For example, a sentence like interakciju sa korisnikom expresses “interaction with the user.” The nominative form korisnik is used when the user is the subject of a sentence.

In computing and IT contexts, korisnik is the standard term for “user,” and its instrumental form korisnikom appears in documentation, interface strings, and localization where the action involves or is performed by the user. It is not typically used as a stand-alone subject; rather, its instrumental form appears within phrases describing interactions, permissions, or collaborations with the user.
