Vehicle I got rid of has ceased to exist (8)
I believe the answer is:
vanished
'ceased to exist' is the definition.
I can't judge whether this defines the answer.
'vehicle i got rid of' is the wordplay.
'vehicle' becomes 'van' (type of vehicle).
'got rid of' becomes 'shed' (shed can mean to lose or cast off).
'van'+'i'+'shed'='VANISHED'
'has' is the link.
Can you help me to learn more?
(Other definitions for vanished that I've seen before include "Disappeared without trace" , "disappeared from view" , "gone" , "disappeared from sight" .)
