Doctor adored Liberal woman past her prime? (3,4)
I believe the answer is:
old dear
'woman past her prime?' is the definition.
(term for an elderly woman)
'doctor adored liberal' is the wordplay.
'doctor' indicates an anagram.
'liberal' becomes 'l' (abbreviation).
'adored'+'l'='adoredl'
'adoredl' anagrammed gives 'OLD DEAR'.
(Other definitions for old dear that I've seen before include "Senior citizen" , "Patronising term for an elderly woman" , "Granny" , "Perhaps Grandma's" .)
