Possessive words that don’t need an apostrophe
Personal pronouns (words like I, you, he, she, it, we, they) indicate the possessive by becoming a whole new word. These words already show possession, so they don’t need an apostrophe: my, mine, your, yours, his, her, hers, its, our, ours, their, theirs.
- The bag is yours.
- My friend’s dog broke its leg.
- It’s not my book, it’s hers.
- The book isn’t mine, it’s theirs.
It’s means it is or it has. You cannot say its’
2. To show that there are missing letters in the middle of words or phrases
- You can’t have my pen, I need it. = You can not have my pen….
- Don’t do that please… = Do not do that….
- I’d like a burger, please. = I would like a burger….
