Cats book in for cosmetics? (7)
I believe the answer is:
lotions
'cosmetics?' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'cats book in' is the wordplay.
'cats' becomes 'lions' (lion is a kind of cat).
'book' becomes 'ot' (Old Testament).
'in' is an insertion indicator.
'lions' going around 'ot' is 'LOTIONS'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for lotions that I've seen before include "Cosmetic preparations" , "Liquid preparations for the skin" .)
