Set fire to the church on the hill! (5)
I believe the answer is:
'set fire to' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for torch that I've seen before include "Small portable battery-powered electric lamp" , "Light carried in the hand" , "Set fire to; electric lamp" , "Small hand-held battery lamp" , "Portable light; burn" .)
