In earlier times, a good man (5)
I believe the answer is:
prior
'man' is the definition.
(I have seen 'holy man' mean 'prior' so perhaps 'man' could also mean 'prior')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for prior that I've seen before include "English keeper" , "Former - holy man" , "Certainly not succeeding" , "Source of poetry in 17th century" , "Former - cleric" .)
