Feel a need for wife to meet social worker (4)
I believe the answer is:
want
'feel a need' is the definition.
'wife to meet social worker' is the wordplay.
'wife' becomes 'w'.
'to meet' means one lot of letters go next to another.
'social worker' becomes 'ant' (I've seen this before).
'w'+'ant'='WANT'
'for' is the link.
(Other definitions for want that I've seen before include "Wish" , "Crave" , "poverty" , "Desire to possess" , "Lack, desire" .)
