Music genre for example, a type of jazz that's retro (6)
I believe the answer is:
garage
'music genre' is the definition.
(I've seen this before)
'example a type of jazz that's retro' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'type of jazz' becomes 'rag' (I can't justify this - if you can you should give a lot more credence to this answer).
'that's retro' shows that the letters should be reversed in order (retro is Latin for 'backwards').
'eg'+'a'+'rag'='egarag'
'egarag' in reverse letter order is 'GARAGE'.
'for' is the link.
Can you help me to learn more?
(Other definitions for garage that I've seen before include "Car repair shop" , "Domestic shelter for car" , "Place where cars are serviced" , "Storage building for cars" , "Observation" .)
