Old wanderer, during race, is an exhibitionist (9)
I believe the answer is:
extrovert
'an exhibitionist' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'old wanderer during race' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'wanderer' becomes 'rover' (synonyms).
'during' means one lot of letters goes inside another.
'race' becomes 'tt'.
'rover' inserted inside 'tt' is 'trovert'.
'ex'+'trovert'='EXTROVERT'
'is' is the link.
Can you help me to learn more?
(Other definitions for extrovert that I've seen before include "Person who is more interested in the world than the inner self" , "Person who is outward-looking" , "Outgoing rather than inward-looking" , "Lively and outgoing person" , "Sociable, outgoing person" .)
