The Franks were mostly Germanic which is why English is considered a Germanic language and why Lingua Franca is a thing and why I can riff on the French (Franks) language being English as a silly joke.
English absorbs vocabulary from wherever and whomever it touches because it abhors a vacuum. I will give you a gold star if you can tell me how many languages I have referenced in that last sentence, and this one.
Byzantine Constantinople, I think, and the Fatimid Empire along the Mediterranean coast to the east. I could have said "Anatolia", but I didn't care to (to be Frank).
