Did this genius change, getting recognised? (13)
I believe the answer is:
distinguished
'recognised?' is the definition.
('distinguish' can be a synonym of 'recognize')
'did this genius change' is the wordplay.
'change' indicates an anagram.
'did'+'this'+'genius'='didthisgenius'
'didthisgenius' anagrammed gives 'DISTINGUISHED'.
'getting' acts as a link.
(Other definitions for distinguished that I've seen before include "Treated as different" , "Recognised - famous" , "Made out; noble" , "Uniquely recognised" , "Acclaimed" .)
