Where is the word jeans from?

Jeans are made of a material called denim. The name “denim” comes from the name of a sturdy fabric called “Serge de Nîmes”, initially made in Nîmes, France, hence “de Nîmes” – “denim”. Weavers of Nîmes tried to reproduce the cotton corduroy that was famously made in the city of Genoa, in Italy, but with no luck.
