I want some explanation about objective pronouns as it is not given in the video..............
Objective pronouns are personal pronouns.
Pronouns that are written after the verb or at the object place are known as objective pronouns. They are 'him', 'her', 'me', 'us', 'you', 'them', etc.
Few sentences with their usage are:
1. I will ask him to bring the grocery.
2. Take me to a party.
3. Please talk to him before he leaves for work.
4. He bought her a beautiful dress.
