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 quite see how this works, but
'person' could be 'raver' (raver is a kind of person) and 'raver' is found in the answer.
This explanation may well be incorrect...
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?" .)
