Look for quiet in a religious order (6)
I believe the answer is:
aspect
'look' is the definition.
('aspect' can be a synonym of 'look')
'quiet in a religious order' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'in' means one lot of letters goes inside another.
'religious order' becomes 'sect' ('sect' can be a synonym of 'religious order').
'a'+'sect'='asect'
'p' going inside 'asect' is 'ASPECT'.
'for' is the link.
(Other definitions for aspect that I've seen before include "Face" , "Particular part or feature of something" , "Standpoint" , "Viewpoint, feature to be considered" , "Distinct part or element" .)
