Had become conscious of what's good in various ways (5)
I believe the answer is:
woken
'had become conscious of' is the definition.
I can't judge whether this defines the answer.
'good in various ways' is the wordplay.
'good' becomes 'ok'.
'in' indicates putting letters inside.
'various ways' becomes 'wen' (I am not sure about this - if you are sure you should believe this answer much more).
'ok' put within 'wen' is 'WOKEN'.
'what's' is the link.
Can you help me to learn more?
(Other definitions for woken that I've seen before include "Roused from sleep" , "Aroused" .)
