Rule reminder
'Sentire' = to hear (subjective, everyday, colloquial — implies the listener was present and perceived the sound). 'Udire' = to hear (more objective, formal, literary — often implies the sound reached one's ears, with less emphasis on the listener's engagement). Udire is rare in spoken Italian but common in literary, legal, and journalistic contexts.
