Usage notes
- Use 'quando' for direct questions (Quando arrivi?), not 'a che ora' (time-specific).
- In indirect questions, keep subject-verb order: 'Non so quando arriva' (not 'quando lui arriva').
- Avoid mixing up 'quando' (time) with 'perché' (reason) in answers: 'Quando?' asks 'when?', not 'why?'.
