We had married (3)
I believe the answer is:
wed
'married' is the definition.
('wed' can be similar in meaning to 'married')
'we had' is the wordplay.
'had' becomes 'd' (I've seen this in other clues).
'we'+'d'='WED'
(Other definitions for wed that I've seen before include "Join" , "Joined in the dew" , "Took in marriage" , "Unite closely" , "united" .)
