Lover who may be married? (7)
I believe the answer is:
admirer
'lover' is the definition.
(I know that admirer is a type of lover)
'may be married?' is the wordplay.
'may be' indicates an anagram.
'married' is an anagram of 'ADMIRER'.
'who' acts as a link.
(Other definitions for admirer that I've seen before include "Suitor; devotee" , "potential suitor" , "A young lady's beau - he thinks she's great" , "girlfriend?" , "sweetheart" .)
