Drink before work showing conscience? (8)
I believe the answer is:
superego
'conscience?' is the definition.
(I know that superego is a type of conscience)
'drink before work' is the wordplay.
'drink' becomes 'sup' (to sup is to drink).
'before' becomes 'ere' (poetic term).
'work' becomes 'go' (synonyms).
'sup'+'ere'+'go'='SUPEREGO'
'showing' is the link.
(Other definitions for superego that I've seen before include "Part of the unconscious mind - pose urge (anag)" , "self-critic" , "Freud's part of the mind that acts as a self-critical conscience" , "Internal monitor of psyche" , "Moral part of the (Freudian) unconscious" .)
