Doctor married her fiancé, presumably (7)
I believe the answer is:
admirer
'her fiance presumably' is the definition.
I can't judge whether this definition defines the answer.
'doctor married' is the wordplay.
'doctor' indicates anagramming the letters.
'married' with letters rearranged gives 'ADMIRER'.
Can you help me to learn more?
(Other definitions for admirer that I've seen before include "Married to one who cherishes" , "Married (anag) -- lover" , "Fan or devotee" , "Supporter or suitor" , "A young lady's beau - he thinks she's great" .)
