I chose my title to conform with subreddit policy, and while I am first and foremost interested in the details of the first meeting of the French and English, I am also very open to details involving the first encounters of other civilizations.
Again, my primary interest is in the methods used by foreign nations to acquaint themselves with the language/s of others.
hi! I don't recall having seen any posts asking about overcoming language barriers between French and English (or, Norman French and Anglo-Saxon, if that's more what you're interested in), so hopefully someone can drop by with some info on that. Meanwhile, get started on this more general section in the FAQ*
Cross-cultural communication and lingua francas
