Extraordinary tiredness in person expressing resistance (9)
I believe the answer is:
dissenter
'person expressing resistance' is the definition.
I can't tell whether this definition defines the answer.
'extraordinary tiredness' is the wordplay.
'extraordinary' is an anagram indicator.
'tiredness' is an anagram of 'DISSENTER'.
'in' is the link.
Can you help me to learn more?
(Other definitions for dissenter that I've seen before include "One who differs among residents" , "One expressing disagreement" , "One who objects" , "one not C of E" , "One who disagrees out of tiredness" .)
