Was bound to be outwitted (3)
I believe the answer is:
had
'be outwitted' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for had that I've seen before include "kept" , "Possessed; cheated" , "Was bound to be - caught" , "Taken in" , "Was in possession of" .)
