You can wear it right next to the fire (6)
I believe the answer is:
blazer
'you can wear it' is the definition.
I can't tell whether this definition defines the answer.
'right next to the fire' is the wordplay.
'right next' becomes 'r' (I've seen this in other clues).
'to' means one lot of letters go next to another (I've seen this in other clues).
'the fire' becomes 'blaze' (blaze is a kind of fire).
'r' put after 'blaze' is 'BLAZER'.
Can you help me to learn more?
(Other definitions for blazer that I've seen before include "First to trail" , "Light single-breasted (school or club) jacket" , "coat?" , "Loose-fitting jacket for school or team" , "Type of jacket for sports officials" .)
