Diagnose current depression -- condition society ultimately supports (8)
I believe the answer is:
identify
'diagnose' is the definition.
(I've seen this before)
'current depression condition society ultimately supports' is the wordplay.
I cannot quite see how this works, but
'current' could be 'i' (symbol for electric current) and 'i' is located in the answer.
'depression' could be 'dent' (dent is a kind of depression) and 'dent' is found in the answer.
'condition' could be 'if' (I've seen this in other clues) and 'if' is present in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for identify that I've seen before include "Recognise as specific person or thing" , "Pinpoint" , "Establish who someone is, put name to" , "Empathise" , "Establish who one is" .)
