Walk proudly (5)
I believe the answer is:
strut
'walk proudly' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for strut that I've seen before include "(Walk with) a stiff pompous gait" , "Bar; walk stiffly" , "Supportive member" , "Stiffening bar" , "Walk proudly like peacock" .)
