Definition: Genitive refers to a term that refers to either a specific or a personal person, depending on their gender. The genitive form of nouns like "John," "Sally," and "Mary" can be formed by adding additional elements (such as "is" or "are") at the end of the word, followed by a noun in the case of singular objects, or the subject of another sentence. For example: - John is my brother. - Sally is my girlfriend. In this example, "John" is the genitive form for the name "John," and "Sally" is the genitive form for the personal pronoun "Sally." The "is" added at the end of "sally" specifies that it refers to John as a person.
