Real understanding comes slowly.
People still repeat that mistaken belief even all these years later. I think you've brought up a very interesting and important point here. Certainly everyone agrees that culture and language are closely interconnected. BUT, I think it is important to look carefully at the ways culture interacts with language, and, more to the point perhaps, the ways that it doesn't. For instance, I could write a 100 page book telling you all about how to inflect Latin verbs.
