Browbeaten fellow got married (5)
I believe the answer is:
cowed
'browbeaten' is the definition.
(synonyms)
'fellow got married' is the wordplay.
'fellow' becomes 'co' (eg a co-worker is a fellow worker).
'got married' becomes 'wed' (I've seen this in another clue).
'co'+'wed'='COWED'
(Other definitions for cowed that I've seen before include "Subdued, kept under" , "Overawed" , "Browbeaten" , "Intimidated, subdued" , "Subdued in bovine way?" .)
