So, with your degree in Applied Linguistics, you should be able to answer that question a bit more in depth. Has there ever been any relevance of Chomsky's work in the areas of Applied Linguistics, and if so, which areas were these? You should look at a work called "Language in the Inner City" by Labov, just to give you a little "hint",lol.

Whether it was in Applied Linguistics or not is irrelevant.
