用法筆記

This idiom always takes an object after 'to'. The subject is the person or thing that causes the fire, not the thing that burns. It usually implies deliberate action — unlike 'catch fire', which can be accidental. The passive form 'be set fire to' is also common (e.g. 'The car was set fire to overnight').
