Didn't fail to deal out spades (6)
I believe the answer is:
passed
'didn't fail' is the definition.
(I've seen this in another clue)
'deal out spades' is the wordplay.
'spades' can be anagrammed to 'PASSED'.
But, I'm unsure how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for passed that I've seen before include "'Brought into effect, laws perhaps (6)'" , "Got a good grade" , "Examined and declared satisfactory" , "Failed to bid" , "Succeeded" .)
