Ovaj
Ovaj is a demonstrative determiner used in several South Slavic languages, most notably Croatian, Serbian, Bosnian, and Montenegrin. It signals proximity to the speaker and translates roughly as this or this one in English. Ovaj accompanies a noun and agrees with its gender and number. The basic nominative singular forms are ovaj (masculine), ova (feminine), and ovo (neuter). In the nominative plural, the common forms are ovi (masculine), ove (feminine), and ova (neuter). In other cases, ovaj changes according to standard noun-adjective declension patterns, producing forms such as ovog, ovom, i ovoga, depending on case and grammatical role.
Etymology traces ovoj to the Proto-Slavic demonstrative stem ov- with gendered and case-inflected endings, and cognates
Usage notes emphasize that ovaj functions to specify a particular noun within discourse or to point to
