Outgoing bonus cut? About time! (9)
I believe the answer is:
extrovert
'outgoing' is the definition.
(I've seen this before)
'bonus cut? about time' is the wordplay.
'bonus' becomes 'extra' (I've seen this in another clue).
'cut?' means to remove the last letter (I've seen 'cut' mean this).
'about time' becomes 'overt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'extra' with its final letter removed is 'extr'.
'extr'+'overt'='EXTROVERT'
Can you help me to learn more?
(Other definitions for extrovert that I've seen before include "he's turned out" , "A lively sociable person, always up front" , "Person who is more interested in the world than the inner self" , "Outgoing type" , "Outgoing rather than inward-looking" .)
