Support Religious Instruction, uplifting routine for owner (10)
I believe the answer is:
proprietor
'owner' is the definition.
(I've seen this before)
'support religious instruction uplifting routine' is the wordplay.
'support' becomes 'prop' (prop is a kind of support**).
'religious instruction' becomes 'ri' (abbreviation).
'uplifting' is a reversal indicator.
'routine' becomes 'rote' (I have seen 'Mechanical routine ' mean 'rote' so perhaps 'routine' could also mean 'rote').
'rote' backwards is 'etor'.
'prop'+'ri'+'etor'='PROPRIETOR'
'for' acts as a link.
(Other definitions for proprietor that I've seen before include "Business owner" , "Landlord" .)
