Seek changes in accommodation for minister and be reasonable (4,5)
I believe the answer is:
make sense
'be reasonable' is the definition.
'seek changes in accommodation for minister' is the wordplay.
'changes' indicates anagramming the letters.
'in' indicates putting letters inside.
'accommodation for minister' becomes 'manse' (house assigned to a church minister).
'seek' is an anagram of 'kese'.
'kese' placed into 'manse' is 'MAKE SENSE'.
'and' is the link.
(Other definitions for make sense that I've seen before include "Be understandable or practicable - it's logical" , "Slaughterhouse" , "Be rational" , "Add up" , "Be intelligible" .)
