Wicked, bad character got round you and me (10)
I believe the answer is:
villainous
'wicked' is the definition.
(similar in meaning)
'bad character got round you and me' is the wordplay.
'bad character' becomes 'villain' (villain is a kind of character. I am not sure about the 'bad' bit.).
'got' says to put letters next to each other.
'round' becomes 'o' (o is a circular letter).
'you and me' becomes 'us'.
'villain'+'o'+'us'='VILLAINOUS'
Can you help me to learn more?
(Other definitions for villainous that I've seen before include "Nasty" , "dramatically bad" , "really bad" , "criminal" , "very unpleasant" .)
