Doctor sees end in poverty! (9)
I believe the answer is:
neediness
'poverty' is the definition.
(thesaurus)
'doctor sees end in' is the wordplay.
'doctor' indicates anagramming the letters.
'sees'+'end'+'in'='seesendin'
'seesendin' is an anagram of 'NEEDINESS'.
(Other definitions for neediness that I've seen before include "Poverty" , "Destitution" , "Want" , "Insecurity" , "Wanting state" .)
