In following home, he’s done wrongly (7)
I believe the answer is:
villain
'he's done wrongly' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'in following home' is the wordplay.
'following' means one lot of letters go next to another.
'home' becomes 'villa' (I've seen this before).
'in' put after 'villa' is 'VILLAIN'.
Can you help me to learn more?
(Other definitions for villain that I've seen before include "Bad person in story/play" , "Criminal, rogue" , "Evil character" , "Evil-doer" , "He may rob you" .)
