Grammar : Proper Adjective And Possessive Adjective

The word "his" is a possessive adjective because it shows ownership or possession. It is used to indicate that something belongs to someone. In this case, "his" is used to show that something belongs to a male person. Proper adjectives, on the other hand, are formed from proper nouns and are used to describe or modify proper nouns. Since "his" does not fit this definition, it is not a proper adjective.

In contrast, possessive adjectives are used to show ownership or possession and include words like my, your, his, her, its, our, and their. Since Japanese does not indicate possession, it is not a possessive adjective.
