What does the french lyon mean?

The French word "Lyon" does not have a specific meaning in itself. It's simply the name of the city Lyon, which is located in southeastern France.

The name "Lyon" is thought to have originated from the Celtic tribe Lugdunum, who lived in the region. The name Lugdunum itself likely comes from the Celtic god Lug, who was associated with light and knowledge.

So, while "Lyon" doesn't have a direct translation, its origin is connected to a Celtic god and its meaning is linked to the history and cultural heritage of the region.
