Figure a sheep is sozzled! (3,2)
I believe the answer is:
lit up
'sozzled' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'figure a sheep' is the wordplay.
'figure' becomes 'li' (I can't explain this - if you can you should believe this answer much more).
'a sheep' becomes 'tup' (tup is a kind of sheep).
'li'+'tup'='LIT UP'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for lit up that I've seen before include "like a bulb, perhaps?" , "Prepared to smoke" , "Flashing" , "Drunk (informal)" , "Illuminated (by drink or drugs?)" .)
