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 unsure of the 'confidently' bit.
'unusual trust' is the wordplay.
'unusual' indicates an anagram.
'trust' anagrammed gives 'STRUT'.
'showing' acts as a 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" .)
