The 5 rules to using an apostrophe

The apostrophe can be a tricky thing to get right so the children at Swinemoor Primary School decided to make a film with 5 simple rules for its correct use.


Produced in partnership with Digital Schools.

Rule 1:

To show possession by one owner, add an apostrophe
and the letter s to the owner.

Rule 2:

To show ownership of plural nouns, add an apostrophe after the s.

Rule 3:

Irregular plural possessives – Add an apostrohphe after the owner, then add an s at the end.

Rule 4:

Compound plural possessives – If two people own something together, only use one apostrophe.

Rule 5:

Not every plural noun has an apostrophe!
