Confused agitation or restful confusion (7)
I believe the answer is:
fluster
'confused agitation' is the definition.
'fluster' can be an answer for 'agitation' (thesaurus). I am not certain of the 'confused' bit.
'restful confusion' is the wordplay.
'confusion' indicates anagramming the letters.
'restful' with letters rearranged gives 'FLUSTER'.
'or' acts as a link.
Can you help me to learn more?
(Other definitions for fluster that I've seen before include "Agitate" , "Confuse" , "Ruffle" , "Disconcert" , "Make hot and flurried." .)
