Celebrated fellow loves snubbing Republican (6)
I believe the answer is:
famous
'celebrated' is the definition.
(synonyms)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for famous that I've seen before include "Known and esteemed" , "Renowned, noted" , "Known-of widely" , "Illustrious" , "Known to very many people" .)
