Copernicus ignores puns produced by old consul, governor and orator (6)
I believe the answer is:
cicero
'orator' is the definition.
(I've seen this before)
'copernicus ignores puns produced' is the wordplay.
'ignores' is a deletion indicator.
'produced' is an anagram indicator.
'copernicus' with 'puns' taken away is 'coeric'.
'coeric' anagrammed gives 'CICERO'.
'by old consul governor and' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cicero that I've seen before include "Famous Roman orator" , "Philosopher" , "Old politician" , "Statesman from Rome" , "Marcus Tullius -, Roman consul, orator and writer" .)
