Nouns in Croatian grammar are a fundamental part of the language. They are words that represent people, objects, places, concepts, and ideas. Like in many other languages, nouns in Croatian have gender (masculine, feminine, and neuter) and number (singular and plural).

Croatian nouns decline to display various grammatical functions, such as the subject, direct object, or possessive case. They also change according to the cases (nominative, genitive, dative, accusative, vocative, and locative) and prepositions.

Nouns in Croatian have different word endings that indicate their gender, number, and case. Masculine nouns often end with a consonant, while feminine nouns typically end with -a or -ija. Neuter nouns can end with various letters, such as -o, -e, or -ić.

It is important to learn the gender, number, and declension patterns of nouns in order to use them correctly in Croatian sentences. Nouns are crucial for building sentences and expressing thoughts accurately, making them a crucial aspect of mastering the Croatian language.
