The sign (‘) is called apostrophe. It is used to write contraction; to indicate possession; to indicate the omission of letters in a word or a sentence.
Following are some examples
- He hasn’t eaten lunch. (for has not – to indicate contraction)
- I can’t stand this attitude of John. (for cannot to indicate missing letters)
- I cannot stand John’s this attitude. (of John – to indicate possession)
- He doesn’t care whether I like it or not. (for does not)
- This man’s son left the town only to never come back. (son of man – to indicate possession)
- John’s father died of cardiac arrest. (father of John – to indicate possession)
The apostrophe is also used to write certain words which were once contractions. Example: o’clock
Important Thing: There is exception to the rule of writing the possessive forms, the apostrophe is not used to write the possessive forms of most pronouns.
- Whose book is this? (Not – Who’s book is this?)
- These bags are hers. (NOT These bags are her’s.)
- This bag is yours. (Not – The bag is your’s.)
- I like India for its culture ( not – I like India for it’s culture)
