So true. The very fact that English is primarily a blend between Anglo Saxon and Norman French makes it a goldmine of nuance in word selection, whether I shitteth merrily in a field or defecate on a golden throne.

I love your line re the ethnicity of the Wiki writer. They did cite a text on slang in the foot notes. Though, for an interjection like Yo!, it’s not going to be easy to track in printed language.

I’m pretty sure “yeah” comes from the German “ja”. But now I’m in Maine, so it’s “ayuh.”

Fun to converse!
