Rôle is the apparent correct way to write it back in the day, so that's a loan word. So is coöperation apparently. Wowee i do not have the time to go down etymology rabbit holes but the implications are amusing!!

@nomo cooperation being spelled with a ö is actually an english convention thing rather than a loanword thing—the dots are diereses which indicate the two adjacent vowels should be read as separate syllables (i see it most often in modern english with naïve or noël which semi stuck around for some reason even after it faded out of standard practice)
@nomo i can’t explain rôle though, you’re on your own for that one sorry 😂
@Satsuma thank u english major (presumed) that is pretty cool, i learn new word :D
