Molino is mulino in Italian. Ancient Greek and Latin had similar words starting with mol-. Given the importance of that technology I'm not surprised that the word didn't change much. English' mill is also close to the romance languages. [1]
Port and starboard used to be "babordo" and "tribordo" in Italian but they were replaced by "sinistra" (the very word used to say "left") and "dritta".
