After getting aunt in trouble, Edward is not contaminated (9)
I believe the answer is:
untainted
'not contaminated' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs occasionally mean the same thing.
'after getting aunt in trouble edward' is the wordplay.
'after' is a charade indicator (letters next to each other).
'getting' is a charade indicator (letters next to each other).
'trouble' indicates an anagram.
'edward' becomes 'ted' ().
'aunt' after 'in' is 'inaunt'.
'inaunt' with letters rearranged gives 'untain'.
'untain' put next to 'ted' is 'UNTAINTED'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for untainted that I've seen before include "Virginal" , "without unwanted substances" , "Not polluted" .)
