Soap, water - what next? (9)
I believe the answer is:
godliness
'soap' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for godliness that I've seen before include "religion" , "borders on the hygienic?" , "Piety" , "A virtue" , "Respectful behaviour" .)
