Need to have verse in poetry replaced (7)
I believe the answer is:
poverty
'need' is the definition.
(thesaurus)
'verse in poetry replaced' is the wordplay.
'verse' becomes 'v'.
'in' is an insertion indicator.
'replaced' is an anagram indicator.
'poetry' is an anagram of 'poerty'.
'v' going inside 'poerty' is 'POVERTY'.
'to have' is the link.
(Other definitions for poverty that I've seen before include "Lack of money etc" , "Penury" , "'When ....... comes in at the door, love flies out of the window'" , "Indigence" , "Need" .)
