Knot in Korean (romanized), maedup or maedeup. Po-tae-toe po-tah-toe or more accurately Beijing vs Peking. I first saw it as maedup and still see it as that from time to time, it’s shorter, I like short. Brevity is good. When I’m copying something down and it’s written as maedeup, I’ll copy it that way though. So, no consistency. Sorry.
