What is the classification of nouns and pronouns into three groups: masculine, feminine, and neuter?

The classification of nouns and pronouns into three groups—masculine, feminine, and neuter—is known as gender. Gender provides a way to categorize nouns and pronouns based on the characteristics they denote, such as whether they refer to male beings, female beings, or things that are considered neutral in gender. This classification is important in languages that have gendered structures, as it influences aspects of grammar, including agreement and the form of accompanying adjectives and verbs. Understanding gender helps learners of the language to accurately construct sentences and communicate effectively.
