The Genitive Case in Serbian Grammar is commonly used to indicate possession, quantification, and negation. It helps to specify ‘of whom’ or ‘of what’ something is. The endings change based on the gender (masculine, feminine, neuter) of the words and whether they are in singular or plural form. This case also has important functions in various expressions of time, portion, and measurement. Hence, the Genitive case is integral in forming the structure of the Serbian language.
