In Hindi grammar, articles do not exist in the same way as they do in English. Instead, Hindi uses postpositions, such as का (ka), की (kī), and के (ke), which serve a similar function to articles in English. These postpositions are used to show possession, gender, and number, and are placed after the noun. In this exercise, you will practice using the correct postpositions in Hindi sentences. This will help improve your understanding of Hindi grammar and enhance your language skills.
