Rule reminder
Advanced perception verbs: 'intuire' = to intuit, sense instinctively (non-physical); 'percepire' = to perceive (physical or abstract, more formal); 'avvertire' = to sense/feel (often a threat, sensation, or warning signal — physical or emotional). These add nuance and register beyond semplice vedere/sentire.
Pur non essendo esperto, ___ immediatamente che qualcosa non andava nella sua storia.
