College head priest to settle around five (7)
I believe the answer is:
provost
'college head' is the definition.
(I've seen this in another clue)
'priest to settle around five' is the wordplay.
'priest' becomes 'p' (ecclesiastical abbreviation).
'to settle' becomes 'roost' (roosting is a kind of settling).
'around' is an insertion indicator.
'five' becomes 'V' (Roman numeral).
'roost' going around 'v' is 'rovost'.
'p'+'rovost'='PROVOST'
(Other definitions for provost that I've seen before include "College or cathedral head" , "College head; minister" , "Cathedral dignitary" , "University college head" , "College head - Scots mayor" .)
