A Doctor of Divinity meeting son at university? Makes sense (4,2)
I believe the answer is:
adds up
'makes sense' is the definition.
('add up' can be a synonym of 'make sense')
'a doctor of divinity meeting son at university?' is the wordplay.
'doctor of divinity' becomes 'dd' ('DD' can be a synonym of 'doctor of divinity').
'meeting' says to put letters next to each other.
'son' becomes 's'.
'at university?' becomes 'up'.
'a'+'dd'+'s'+'up'='ADDS UP'
(Other definitions for adds up that I've seen before include "Reckons" , "Sums - makes sense" , "Stands to reason" , "Totals" , "Tots" .)
