Admirer may be wed (7)
I believe the answer is:
married
'wed' is the definition.
(similar in meaning)
'admirer may be' is the wordplay.
'may be' is an anagram indicator.
'admirer' anagrammed gives 'MARRIED'.
(Other definitions for married that I've seen before include "Closely linked" , "9 across (anag)" , "Spliced" , "Conjugal" , "United in match" .)
