What's the literal meaning of 'Nessuno ha sorriso'?"}, {"role": "assistant", "content": "The phrase 'Nessuno ha sorriso' is in the present perfect tense. 'Nessuno' means 'nobody', 'ha' is the third person singular of 'to have' in the present tense, and'sorriso' is the past participle of'sorridere', which means 'to smile'. So the literal meaning is 'Nobody has smiled'."}, {"role": "user", "content": "That makes sense.
