College post could be richer post (10)
I believe the answer is:
rectorship
'college post' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'could be richer post' is the wordplay.
'could be' indicates an anagram.
'richer'+'post'='richerpost'
'richerpost' anagrammed gives 'RECTORSHIP'.
Can you help me to learn more?
(Other definitions for rectorship that I've seen before include "Parson's position" , "church office" , "Clergyman's office" , "Richer post (anag) -- top administrative position in some universities and colleges" .)
