A newly-published dictionary for children has incorporated references to Harry Potter to help young readers understand the meaning of words.
Harry Potter has been a publishing phenomenon
The Oxford Primary Dictionary features hundreds of citations from children's authors including JK Rowling, Philip Pullman and Roald Dahl.
The publisher said using "'real' sentences provides a direct link to children's reading".
The dictionary is aimed at seven- to 11-year-olds.
A citation for the word innumerable cites Harry Potter and the Chamber of Secrets with the sentence "Innumerable candles were hovering in mid-air, over four long crowded table".
As well using citations from modern books, classic novels have also been drawn on, including CS Lewis and Enid Blyton.
Compilers drew on lists of boy and girl-friendly titles to ensure both genders drew as much from the dictionary as possible.
The launch of the dictionary comes just weeks ahead of the release of the eagerly-anticipated Harry Potter and the Half-Blood Prince, the sixth in the wizarding saga.
