A preparation that's liquid, for a change, not oil (6)
I believe the answer is:
lotion
I believe this clue is a quadruple definition!!
'a preparation' is the first definition.
(I have seen 'Medicinal preparation ' mean 'lotion' so perhaps 'preparation' could also mean 'lotion')
'that's liquid' is the second definition.
(I've seen this before)
'for' is a link.
'a change' is the third definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'not' acts as a link.
'oil' is the fourth definition.
(thesaurus)
Can you help me to learn more?
(Other definitions for lotion that I've seen before include "Medicinal wash" , "Embrocation" , "Medicinal liquid applied to skin" , "Medicinal or cosmetic liquid for skin" , "Liquid for washing the skin" .)
