Fascinating Fact:

Use “Jess’s lunchbox” or “Chris’s pencil” the same way, with ’s after names ending in s.

In KS1 English, children learn to use an apostrophe and s to show when something belongs to one person, including names like Ben’s book, Aisha’s bag and Jess’s jumper.

  • Proper noun: A special name for a person, place or thing that starts with a capital letter, like Lucy, London or Tuesday.
  • Apostrophe (’): A punctuation mark used to show missing letters or to show that something belongs to someone.
  • Singular possessive: Using apostrophe + s (’s) to show something belongs to one person or thing, like “Tom’s hat”.
What is a singular possessive apostrophe with proper nouns?

A singular possessive apostrophe with proper nouns shows that something belongs to one named person, using ’s, like “Mia’s pencil” or “Alex’s game”.

Do I use ’s after names that already end in s?

Yes. In KS1 we usually add ’s even if the name ends in s, like “Jess’s lunchbox” or “James’s coat”, to make the ownership clear.

How can I teach children to spot possessive apostrophes in names?

Ask “Who does it belong to?” If the answer is one person’s name, write the name then add ’s, for example “Layla’s bag” or “Chris’s ball”.

James' new shoes were brilliant. Why don't we need to write James's?
Because James doesn't like too many 's' in his name.
Because it would take too long to add the extra 's'.
If a name ends in an 's' then you only need to add an apostrophe to show possession.
If a name ends in an 's' then they don't own anything.
You have a choice. If a name ends in 's' you can either write it this way: James'; or this way: James's. Both are correct but the preferred way tends to be James'.

This is Anne's new watch.

Because his name is Johns.
To show that the kite belongs to John.
