Sickened by a nude sprawled around chair (9)
I believe the answer is:
nauseated
'sickened' is the definition.
('nauseate' can be a synonym of 'sicken')
'a nude sprawled around chair' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'chair' could be 'seat' (something to sit on) and 'seat' is located in the answer.
an anagram of 'nude' is 'nued' which is located in the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'by' acts as a link.
Can you help me to learn more?
(Other definitions for nauseated that I've seen before include "Sickened" , "Disgusted" , "Revolted" .)
