Never right, agriculturalist comes to prominence (4)
I believe the answer is:
fame
'to prominence' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fame that I've seen before include "Renown, celebrity" , "Note" , "Notoriety or celebrity" , "Celebrity; stage musical" , "Favourable public reputation" .)
