Hello Iris, 'Eurgh' is not a real word but a sound we make when something happens that we don't want or don't expect. The first part is like 'er' at the end of computer and the end is a 'g'. There doesn't seem to be common agreement on this on as it is a sound rather than a word!

It's a kind of 'er-uh' sound composed entirely of vowels. You can say it how you like, so long as you sound disgusted!

Thanks.

I always think of Monty Python's doctor sketch when I see "Eurgh!" (at about the 54-second mark): http://www.youtube.com/watch?v=jWMO3rAD98k
