Why do so many people from Louisiana talk with a dialect like they are from the northern states?

Answer 1

The Acadia and French Creole culture (and dialect) was transplanted to Louisiana from Canada in the 1760's after the French and Indian War (or as Europeans call it, 'The Seven Years War').

In 1755, Britain forcibly removed 12,000 French settlers from Nova Scotia (then-Acadia) and sent them to France, or to other British colonies, or to prison. Others eventually resettled to Louisiana on their own account, following the French surrender of Montreal to the British in 1760.

To this day, you can find some of the same dialects and architecture in the Canadian Maritime Provinces (Acadia) as you can in Louisiana. Acadians are known as Cajuns today.

Answer 2

I'll bet you didn't know that much of Louisiana was inhabited by the Creole peoples. These people left Nova Scotia, Canada because of the persecution to them there and settled in Louisiana. I suspect that this accent is partially what you hear in the Louisianan dialect.

Answer 3

I think it's the local dialect. I've heard some people describe New Orleans accents as Brooklyn accents with a southern drawl.

Answer 4

Because I live in Louisiana now, but came from Cleveland OHIO
CLEVELAND ROCKS

Answer 5

That's not what I hear when they speak.
