Unpleasant aftermath hidden by Callaghan government (8)
I believe the answer is:
hangover
'unpleasant aftermath' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'hidden by callaghan government' is the wordplay.
'hidden' indicates a hidden word.
'HANGOVER' is hidden in the letters of 'by callaghan government'.
Can you help me to learn more?
(Other definitions for hangover that I've seen before include "Morning-after problem" , "morning-after feeling?" , "Effect of previous day's alcohol" , "problem arising?" , "After-effects of excessive drinking" .)
