Men a bit nasty on all sides (7)
I believe the answer is:
ambient
'men a bit nasty on all sides' is the definition.
I can't tell whether this defines the answer.
'men a bit nasty' is the wordplay.
'nasty' indicates anagramming the letters (a nasty or wrong spelling).
'men'+'a'+'bit'='menabit'
'menabit' anagrammed gives 'AMBIENT'.
Can you help me to learn more?
(Other definitions for ambient that I've seen before include "Surrounding or encircling, say temperature" , "sort of music" , "relaxed atmosphere" , "Relating to the immediate environment" , "Relating to the immediate surroundings" .)
