Where do we get the word denim from ?

If you have a pair of Jeans you will know that what they are made of is called denim, but do you know where the word comes from?
At first, it was used to describe a serge cloth made in Nimes, France – the original name was ‘serge de Nimes’. Gradually, these last two names were shortened and adapted to the word we know as denim, although now denim is made all over the world sand not just in Nimes.
