It’s not really a surprise that the inclusion of quidditch in the latest Oxford Dictionaries online update has garnered so much publicity. After all, Harry Potter is an international phenomenon, quidditch is now known the world over, as a word it is very well established.

Of course, it is not JK Rowling’s mythical game which has been recognised by the Oxford experts. Instead, it is the real-world equivalent, played by people who mount broomsticks and run around a field, throwing balls through hoops in a grounded version of the game popularised in the skies of Hogwarts. Such is the popularity of real-life Quidditch that there are two competing authorities in the United States responsible for tournaments, rules and so on, while the rapid worldwide growth of the game since it was first played in 2005 attests to not only the enduring popularity of Potter but also to the fact that it is evidently enjoyed by those who take part.

The reasoning for its inclusion is therefore completely sound – a new sport, now established, with a name that needs to be recorded. I guess the irony for a lot of people is that they are not actually aware of this version, and will have assumed that it was the fictional equivalent which had received lexicographical recognition. Which of course would not have happened.

Nevertheless, I wonder whether there is a certain uniqueness to the word quidditch. Words from fiction are a well known source of neologisms – the latest Oxford update includes cromulent, coined on The Simpsons, and embiggen, popularised on the same programme. But they are words which are used with the meaning which they have carried over from their TV appearances.

It is not just that the quidditch immortalised in the dictionary is different to the original fictional version. It is that something in fiction has inspired the creation of a real-world equivalent, and it is the real-world equivalent which is now recognised. I am trying to think of another example of something created in fiction which has subsequently been made real and then gone on to become established in the language in its new incarnation.

I am not coming up with anything else, but I am happy to be corrected. If anybody can think of other examples, please leave them in the comments below.
