Change of route that means deviating from normal (5)
I believe the answer is:
outre
'deviating from normal' is the definition.
(I've seen this before)
'change of route' is the wordplay.
'change of' indicates anagramming the letters (the letter order is changed).
'route' anagrammed gives 'OUTRE'.
'that means' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for outre that I've seen before include "Far out - in France" , "Outrageous" , "Bizarre or eccentric in France" , "over the top" , "deviating from the norm" .)
