One can rave about European wandering (9)
I believe the answer is:
itinerant
'european wandering' is the definition.
'itinerant' can be an answer for 'wandering' (I've seen this before). I am unsure of the 'european' bit.
'one can rave' is the wordplay.
'one' becomes 'i' (Roman numeral).
'can' becomes 'tine' (I can't explain this - if you can you should give a lot more credence to this answer).
'rave' becomes 'rant' (synonyms).
'i'+'tine'+'rant'='ITINERANT'
'about' is the link.
Can you help me to learn more?
(Other definitions for itinerant that I've seen before include "Wanderer" , "Moving from place to place" , "(Person) on the move" , "Rambling" , "Travelling from place to place" .)
