In Kannada grammar, nouns are categorized into three types based on their gender: male (ಪುರುಷ), female (ಸ್ತ್ರೀ), and neuter (ನಪುಂಸಕ). The gender of a noun often affects other parts of the sentence, such as adjectives and pronouns. Understanding and correctly identifying the gender of a noun is crucial to maintaining accurate grammar in the Kannada language.
