Walk like a peacock (5)
I believe the answer is:
strut
'walk like a peacock' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for strut that I've seen before include "Move stiffly" , "Compression member; walk stiffly" , "Supporting rod" , "Stiffening bar" , "Vain walk" .)
