The'me ne' part is an idiomatic expression that implies leaving a place, and 'devo' means 'I must', 'andare' means 'to go', and 'presto' means 'early' or'soon'."}, {"role": "user", "content": "I see, that makes sense.

'Mi dispiace, ma me ne devo andare presto' means 'Sorry, but I must leave early.' The added'mi dispiace' (sorry) makes the sentence more polite and considerate of your host's feelings."}]
