Pulverise badly and make ugly (9)
I believe the answer is:
repulsive
'ugly' is the definition.
(I've seen this before)
'pulverise badly' is the wordplay.
'badly' indicates anagramming the letters.
'pulverise' is an anagram of 'REPULSIVE'.
'and make' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for repulsive that I've seen before include "ugly" , "Disgusting" , "Obnoxious" , "Loathsome" , "Abhorrent" .)
