Come out of hiding to smash the disguise, perhaps (5,5)
I believe the answer is:
break cover
'come out of hiding' is the definition.
(I've seen this before)
'smash the disguise perhaps' is the wordplay.
I cannot really see how this works, but
'smash' could be 'break' (I've seen this before) and 'break' is present in the answer.
'disguise' could be 'cover' (cover can mean a disguise or secret identity) and 'cover' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for break cover that I've seen before include "Come out of hiding" , "Be clearly out" , "Come in to open" .)
