Garment right behind fire (6)
I believe the answer is:
blazer
'garment' is the definition.
(blazer is a kind of garment)
'right behind fire' is the wordplay.
I cannot really understand how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
'fire' could be 'blaze' (blaze is a kind of fire) and 'blaze' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for blazer that I've seen before include "Sportsman's jacket" , "School jacket (on fire?)" , "Type of jacket for sports officials" , "Summer sporting jacket" , "Man's garment" .)
