Peacock in mating frenzy on the way (5)
I believe the answer is:
strut
'peacock' is the definition.
(I've seen this before)
'in mating frenzy on the way' is the wordplay.
'in mating frenzy' becomes 'st' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' is a charade indicator (letters next to each other).
'the way' becomes 'rut' (rut is a kind of way).
'st'+'rut'='STRUT'
Can you help me to learn more?
(Other definitions for strut that I've seen before include "supporter" , "Display arrogance" , "Rigid support" , "Prop; prance" , "Walk proudly; bar" .)
