Mark left by damage to socialist leader's vehicle (4)
I believe the answer is:
hack
I believe this is a sextuple definition!!!
'mark' is the first definition.
(thesaurus)
'left' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'by' acts as a link.
'damage' is the third definition.
(thesaurus)
'to' is a link.
'socialist' is the fourth definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'leader's' is the fifth definition.
(hack is a kind of leader)
'vehicle' is the sixth definition.
(I know that hack is a type of motor car)
Can you help me to learn more?
(Other definitions for hack that I've seen before include "try to access unauthorised data" , "Cut roughly; journalist" , "Chop - reporter" , "Kick on the shins" , "Ride" .)
