University administrator may find source of agreement in study (4)
I believe the answer is:
dean
'university administrator' is the definition.
(I've seen this in another clue)
'source of agreement in study' is the wordplay.
'source of' says to take the initial letters.
'in' indicates putting letters inside.
'study' becomes 'den' (term for a study or office).
The first letter of 'agreement' is 'a'.
'a' going into 'den' is 'DEAN'.
'may find' acts as a link.
(Other definitions for dean that I've seen before include "University officer" , "James ..., film actor" , "Senior academic administrator" , "Ice dancer" , "A senior clergyman - Swift was one" .)
