Extrovert is leaving (8)
I believe the answer is:
outgoing
This clue is a double definition.
'extrovert' is the first definition.
(thesaurus)
'is leaving' is the second definition.
(thesaurus)
(Other definitions for outgoing that I've seen before include "Expenditure" , "At ease in talking to others, extroverted" , "Friendly and sociable" , "Extrovert" , "Friendly - retiring" .)
