Way out route is redefined (5)
I believe the answer is:
outre
'redefined' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives sometimes mean the same thing.
'way out route' is the wordplay.
'way out' indicates an anagram.
'route' with letters rearranged gives 'OUTRE'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for outre that I've seen before include "Deviating from what is proper" , "Strange" , "Abnormal" , "Not abiding by what is proper" , "Shockingly unusual" .)
