Studying disease? Never alone, generally discontented (8)
I believe the answer is:
nosology
'studying disease?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'never alone generally discontented' is the wordplay.
'never' becomes 'no' (I've seen this in other clues).
'alone' becomes 'solo' (as in a musical solo).
'discontented' suggests removing the centre (the word's contents are removed).
'generally' with its middle taken out is 'gy'.
'no'+'solo'+'gy'='NOSOLOGY'
Can you help me to learn more?
(Other definitions for nosology that I've seen before include "The study of diseases" , "classification of disease" .)
