Here are a few of mine:
- The only one coming to my mind that isn't a place name: the English word "meme". I'm largely unused to /iːm/ being spelled <eme> at the end of a single-syllable word, so what often happens is that my brain wants to treat it as a borrowing of the French "même" and pronounce it the same way as "maim". (And that somehow doesn't stop me from treating "crème" as a spelling variant of "cream" in an English-language context despite not having trouble with it in a French-language context.)
- I used to pronounce "Stromboli" with the stress on the second instead of the first syllable.
- I'm inconsistent with the second syllable of "Melbourne". Sometimes I pronounce it right given my rhotic accent (i.e. like "burn"); sometimes I pronounce it like "born".
- The annoying-as-hell "Edinburgh", which I originally thought was pronounced "Eden-berg".
