Wines displayed strength (5)
I believe the answer is:
sinew
'strength' is the definition.
(I know that sinew is a type of strength)
'wines displayed' is the wordplay.
'displayed' indicates anagramming the letters (letters displayed in another way).
'wines' with letters rearranged gives 'SINEW'.
(Other definitions for sinew that I've seen before include "Tendon, for example" , "fibre" , "Strength; tendon" , "power source" , "It indicates strength" .)
