Outgoing person is greener? (9)
I believe the answer is:
extravert
'outgoing' is the definition.
(I've seen this before)
'person is greener?' is the wordplay.
I cannot really see how this works, but
'person' could be 'raver' (raver is a kind of person) and 'raver' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for extravert that I've seen before include "Outward-looking" , "Outgoing" , "showing off, technically?" , "one must look out" , "cordial?" .)
