Was notedly fidgety! (7)
I believe the answer is:
fiddled
'fidgety' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives can sometimes define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fiddled that I've seen before include "cheated" , "What Nero did while Rome burned" , "wasted time" , "Was corrupt" .)
