Revolted by appalling denim clothing infection (8)
I believe the answer is:
mutinied
'revolted' is the definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'appalling denim clothing infection' is the wordplay.
'appalling' indicates anagramming the letters (an appalling spelling).
'clothing' indicates putting letters inside (some letters cover up or clothe others).
'infection' becomes 'uti' (I can't justify this - if you can you should believe this answer much more).
'denim' is an anagram of 'mnied'.
'mnied' placed around 'uti' is 'MUTINIED'.
'by' is the link.
Can you help me to learn more?
