Liquid preparation applied to lion (6)
I believe the answer is:
lotion
'liquid preparation' is the definition.
'lotion' can be an answer for 'preparation' (I have seen 'Medicinal preparation ' mean 'lotion' so perhaps 'preparation' could also mean 'lotion'). I am not certain of the 'liquid' bit.
'applied to lion' is the wordplay.
'applied' indicates an anagram (apply the letters).
'to'+'lion'='tolion'
'tolion' with letters rearranged gives 'LOTION'.
Can you help me to learn more?
(Other definitions for lotion that I've seen before include "Liquid equivalent to ointment" , "Soothing liquid preparation" , "Preparation that's applied to the skin" , "Liquid preparation applied to the skin" , "Cosmetic/medical liquid" .)
