Intimidated officer gets married (5)
I believe the answer is:
cowed
'intimidated' is the definition.
(synonyms)
'officer gets married' is the wordplay.
'officer' becomes 'co' (Commanding Officer abbreviation).
'gets' means one lot of letters go next to another.
'married' becomes 'wed' (wed can mean married).
'co'+'wed'='COWED'
(Other definitions for cowed that I've seen before include "Overawed" , "Intimidated, subdued" , "Subdued in bovine way?" , "Browbeaten" , "Subdued, kept under" .)
