Lost end of jacket in fire (5)
I believe the answer is:
blaze
'fire' is the definition.
(I know that blaze is a type of fire)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for blaze that I've seen before include "Pioneer" , "Strong fire" , "Light-coloured marking on a horse's face" , "Burn fiercely" , "Fierce fire" .)
