Occasion to forget married bond (3)
I believe the answer is:
tie
'bond' is the definition.
(I've seen this before)
'occasion to forget married' is the wordplay.
'occasion' becomes 'time' (I've seen this before).
'to forget' suggests deleting specific letters.
'married' becomes 'm'.
'time' with 'm' taken away is 'TIE'.
(Other definitions for tie that I've seen before include "Bind with a cord" , "Failure to win" , "Neckwear item" , "Dead-heat" , "Draw - connection" .)
