Bound to be hit (6)
I believe the answer is:
lashed
I believe this clue is a double definition.
'bound' is the first definition.
(lashing is a kind of binding)
'be hit' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for lashed that I've seen before include "Tied -- beaten" , "Fastened securely" , "Flogged" , "severely punished" , "Verbally attacked" .)
