Challenge accepted: "The stoic young man bid us au revoir and left"
The thing is, English borrows so much from other languages that it's not apparent to English speakers that the words are from other languages.
...
et cetera (etc)
id est (i.e.)
videlicet (viz)
sic
and that's just Latin.
Think about Schadenfreud, Bon appétit, Au revoir, Macho, Amigo, Kindergarten, Uber, Gesundheit, Smorgasbord, Apartheid, Trek...
Honestly, the list goes on and on and on. English speakers use more "borrowed" phrases and words than any other language I can think of.
