What do the Atlantic people speak?

The term "Atlantic people" is not a recognized cultural or linguistic group. It's a very broad term that could refer to people living near the Atlantic Ocean, which encompasses a huge variety of cultures and languages.

To answer your question, you need to be more specific. For example, you could ask:

* What languages are spoken by the people living in the Atlantic coastal regions of North America?

* What languages are spoken by the indigenous peoples of the Atlantic coast of South America?

* What languages are spoken in the countries bordering the Atlantic Ocean in Europe?

Once you specify the geographic region you're interested in, I can give you a more accurate and helpful answer.
