Public touching not the done thing (5)
I believe the answer is:
outre
'the done thing' is the definition.
Both the definition and answer are adjectives.
Perhaps there's an association between them I don't understand?
'public touching' is the wordplay.
'public' becomes 'out' (out can mean released to the public).
'touching' becomes 're' (both can mean concerning or relating to).
'out'+'re'='OUTRE'
'not' acts as a link.
Can you help me to learn more?
(Other definitions for outre that I've seen before include "Odd, bizarre" , "deviating from the norm" , "Not abiding by what is proper" , "over the top" , "flamboyant" .)
