Common Nouns in Serbian grammar, also known as “Opšta imenica”, are a fundamental part of the language structure. They are used to name general things, places, people, etc., and do not specify a particular object or person, unlike proper nouns. The common nouns in Serbian have genders (masculine, feminine, neutral) and can be in different cases (nominative, genitive, dative, accusative, vocative, instrumental, locative).
