Ceremony morally justified, did you say? (4)
I believe the answer is:
rite
'ceremony' is the definition.
(I know that rite is a type of ceremony)
'justified did you say?' is the wordplay.
'justified' becomes 'right ' (I've seen this before).
'did you say?' indicates a 'sounds like' (homophone) clue.
'right' is a homophone of 'RITE'.
'morally' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for rite that I've seen before include "(Words for) ceremony" , "Religious ritual" , "Custom" , "something like mass" , "form of service" .)
