Could you give some examples of how cultures affect languages? It is comprehensible that languages reflect cultures. It would be really helpful if you could provide with at least an example of cultures affecting the way we speak.
The politeness dances undergone by European personal pronouns are a good example of a culture affecting a language. Another would be the rapid changes made to Old English while it was spoken mostly by peasants after the Norman invasion.
This would be a comment above, except that I am no longer allowed to make comments, for some reason, so I'm testing to see whether answers are similarly occluded.
Edit: Apparently not. But I still can't enter comments. Ah, well.
