The very end of party, spilt my soda (8)
I believe the answer is:
doomsday
'the very end' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'party spilt my soda' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'spilt' indicates anagramming the letters.
'my'+'soda'='mysoda'
'mysoda' anagrammed gives 'omsday'.
'do'+'omsday'='DOOMSDAY'
'of' is the link.
Can you help me to learn more?
(Other definitions for doomsday that I've seen before include "Last moment of the world" , "Unhappy time" , "Time of final judgement" , "End of the world, Last Judgement" , "When the world ends?" .)
