Odd Parisian's on concrete (7)
I believe the answer is:
surreal
'odd' is the definition.
(I've seen this before)
'parisian's on concrete' is the wordplay.
'parisian's on' becomes 'sur' (I can't explain this - if you can you should give a lot more credence to this answer).
'concrete' becomes 'real' (associated in meaning).
'sur'+'real'='SURREAL'
Can you help me to learn more?
(Other definitions for surreal that I've seen before include "Odd" , "strange" , "Weird - like Dali's paintings?" , "Bizarre, fantastic" , "Dreamlike, irrational" .)
