As nursing hospital reveals symptoms of illness? (5)
I believe the answer is:
aches
'symptoms of illness?' is the definition.
'aches' can be an answer for 'symptoms' (ache is a kind of symptom). I'm unsure of the 'of illness?' bit.
'as nursing hospital' is the wordplay.
'nursing' means one lot of letters goes inside another.
'hospital' becomes 'che' (I am not sure about this - if you are sure you should believe this answer much more).
'as' placed around 'che' is 'ACHES'.
'reveals' is the link.
Can you help me to learn more?
(Other definitions for aches that I've seen before include "Hurts; yearns" , "Dull prolonged pains" , "sign of suffering" , "Dull persistent pains" , "Pains, hurts" .)
