Walk confidently, showing unusual trust (5)
I believe the answer is:
strut
'walk confidently' is the definition.
'strut' can be an answer for 'walk' (strutting is a kind of walking). I am not sure about the 'confidently' bit.
'unusual trust' is the wordplay.
'unusual' indicates an anagram.
'trust' is an anagram of 'STRUT'.
'showing' is the link.
Can you help me to learn more?
(Other definitions for strut that I've seen before include "Walk arrogantly" , "supporter" , "Bar; walk stiffly" , "Walk proudly like metal support" , "Reinforcing rod" .)
