Apostrophes in contractions

‘Can’t’, ‘don’t’, ‘shan’t’, ‘won’t’, and such don’t cause many problems but personal pronouns with be verbs in contraction can be hard. ‘I’m’, ‘they’re’, ‘he’s’ and ‘she’s’ are easy. ‘You’re’, means ‘you are’ but ‘your’ means ‘belonging to you’. However ‘it’s’ means ‘it is’ but ‘its’ means ‘belonging to it’.

Apostrophes with plurals

Never make a plural with an apostrophe. ‘Mother’s’ does not mean ‘more than one mother’ it means ‘belonging to Mother’.

When you want to indicate possession or ownership of something or things by more than one party or thing use an apostrophe after the word.
