Went in hospital department before daughter (7)
I believe the answer is:
entered
'went in' is the definition.
('enter' can be a synonym of 'go in')
'hospital department before daughter' is the wordplay.
'hospital department' becomes 'ent'.
'before' becomes 'ere' (usually literary).
'daughter' becomes 'd'.
'ent'+'ere'+'d'='ENTERED'
(Other definitions for entered that I've seen before include "Ten deer (anag) - went in" , "moved in" , "Put down" , "Logged; arrived" , "Enrolled or went in" .)
