Staffs English minister's house (5)
I believe the answer is:
manse
'minister's house' is the definition.
(I've seen this before)
'staffs english' is the wordplay.
'staffs' becomes 'mans' (manning is a kind of staffing).
'english' becomes 'e' (abbreviation).
'mans'+'e'='MANSE'
(Other definitions for manse that I've seen before include "Presbyterian minister's residence" , "Ecclesiastical residence" , "Pile of rector'" , "Scottish minister's residence" , "Presbyterian minister's house" .)
