The term West Atlantic describes a whole group of languages that are spoken in...well, guess.
Here's a picture of the world to help you:
I'm sure you all know that West is leftwards, and also that the Atlantic Ocean is the pale blue stuff between the two main clumps of land.

Nuts and Bolts: Atlantic. The ocean isn't named after the Ancient Greek heroine Atalanta, as you'd expect, but after the Ancient Greek titan Atlas. The Greek pelagos Atalantikos, sea of Atlas, was so named because it lay beyond the Atlas Mountains.
Well, it doesn't, really, for most people (including Greeks) but, hey...
