Bound to have spirit (5)
I believe the answer is:
laced
'bound' is the definition.
(lacing is a kind of binding)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for laced that I've seen before include "Drinks may be" , "with extra spirit" , "reprimanded" , "Tied firmly" , "Intertwined" .)
