Nasty noisy rebuke or scolding (7)
I believe the answer is:
fearful
'nasty' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'noisy rebuke or scolding' is the wordplay.
I cannot really see how this works, but
'noisy' could be 'f' and 'f' is found within the answer.
'rebuke' could be 'earful' (earful is a kind of rebuke) and 'earful' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fearful that I've seen before include "Scared" , "Apprehensive, worried" , "Timorous; terrible" , "Timid" , "Afraid; very great" .)
