Conform to reason following groundbreaking realisation (11)
I believe the answer is:
rationalise
'conform' is the definition.
Both the definition and answer are verbs in their base form.
Perhaps they are linked in a way I don't understand?
'reason following groundbreaking realisation' is the wordplay.
'realisation' can be anagrammed to 'RATIONALISE'.
However, I'm not sure how this is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for rationalise that I've seen before include "Justify with logic" , "Reorganise logically" .)
