When to use apostrophe (')
1. An apostrophe is often used to show that something belongs to someone.
Example:
1. This is Jane's book.
2. The dog's supper is ready.
2. If the word ends with 's' (for example with a plural) the apostrophe comes after the 's'.
Example:
1. The dogs' suppers are ready.
2. The Browns' wedding anniversary is this weekend.
3. An apostrophe is not used with 'ours' or 'yours'. Like 'his' and 'hers' these are already possessives.
Example:
1. These books are ours.
2. I think this box is yours.
4. An apostrophe is used to show possession with: someone, somebody, everyone, everybody.
Example:
1. There is somebody's camera over there.
2. Is that anyone's?
5. An apostrophe is used to replace missing letters. For example: don't (do not), I'm (I am), He's (He is), We'll (We will). 'It's' has an apostrophe when it is replacing 'It is' but not when it is a possessive.
Example:
1. I'm going to the cinema this evening.
2. He's late.
