Fatigue confuses both residents and dissenter (9)
I believe the answer is:
tiredness
'fatigue' is the definition.
(I know that fatigue can be written as tiredness)
'confuses both residents and dissenter' is the wordplay.
'residents' anagrams to 'TIREDNESS'.
Though, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for tiredness that I've seen before include "Lassitude; residents (anag.)" , "7 (anag)" , "Weary feeling" , "Residents in state of fatigue" , "That's liable to occur at midnight" .)
