What does la rochelle mean translated into English?

"La Rochelle" is a French city and doesn't translate directly into English. It's the name of the city itself, like "London" or "Paris."

However, if you want to understand the meaning behind the name, it comes from the Old French words "la" (the) and "roche" (rock), making it literally "the rock." This likely refers to the rocky coastline where the city was founded.
