Could her ploy be spoiled by extravagant claims? (9)
I believe the answer is:
hyperbole
'claims?' is the definition.
(I have seen 'Exaggerated claims' mean 'hyperbole' so perhaps 'claims' could also mean 'hyperbole')
'could her ploy be spoiled by extravagant' is the wordplay.
'her ploy be' can be anagrammed to 'HYPERBOLE'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for hyperbole that I've seen before include "Exaggerated claims" , "not to be taken literally" , "Exaggerated talk from boy helper" , "Deliberate exaggeration used for effect" , "The use of exaggeration for effect" .)
