The apostrophe (’) is the most commonly misused punctuation mark.
Why do we use apostrophes?
1. to show that one or more letters have been missed out in a word (contractions)
2. to show that something belongs to someone (possession)
They are used for two purposes:

“I can’t do my homework tonight ’cause I don’t have my text book and, anyway, it’s not due ’til Monday.”
“I cannot do my homework tonight because I do not have my text book and, anyway, it is not due until Monday.”
We use contractions when speaking because they save time. They make our speech sound informal and conversational.
Contractions
Why do you think contractions are used?
Read the following statement.
How would it sound if no contractions were used?
Contractions should be avoided in formal writing such as essays and letters, as they make the
text sound too casual.

Apostrophes are also used to show possession (who or what owns something).
Apostrophes to show possession
Singular possession is shown by adding an apostrophe and then an ‘s’ to the end of a noun (a person, animal, place or thing).
Tom’s skateboard the dog’s bowl
the car’s tyres

Jo is listening to Tess’s music. ORJo is listening to Tess’ music.
When a singular noun already ends in ‘s’, we can add an apostrophe and then an ‘s’ to show possession OR we can just add an apostrophe.
Possession with singular nouns ending in ‘s’
All of the bus’s seats are full. ORAll of the bus’ seats are full.
For example:
This form is more commonly used because it looks less clumsy, but either form is
acceptable. The key is to be consistent!

To show possession with a plural noun we just add an apostrophe to the end of the word.
Some plural nouns don’t end in ‘s’. For example, ‘children’.In this case, both an apostrophe and an ‘s’ are added to show possession: ‘the children’s playground’.
Plural possession
Can you think of any other plural nouns that do not end in ‘s’?
1. Both the films’ soundtracks are excellent.
2. The girls’ skill at football has improved a lot.
We do not add an extra ‘s’ to a plural nounbecause, in general, we do not pronounce it.

Possessive pronouns
The exception to the apostrophe rule are these possessive pronouns which show possession without apostrophes:
not your’s
not he’s
not her’s
not it’s
not our’s
not their’s
not who’s Whose football is it?

Many people get confused about when to use ‘it’s’ and when to use ‘its’.
‘It’s’ is used only for the contraction of the words ‘it is’.
‘It’s’ – an exception
Do you know when to use each form?
‘Its’ is used to show possession.
It is too late to change your order.It’s too late to change your order.
