A person who destroys vehicle lad picked up (6)
I believe the answer is:
vandal
'a person who destroys' is the definition.
'vandal' can be an answer for 'a person' (vandal is a kind of person). I'm not sure about the remainder of the definition.
'vehicle lad picked up' is the wordplay.
'vehicle' becomes 'van' (type of vehicle).
'picked up' says the letters should be written backwards.
'lad' in reverse letter order is 'dal'.
'van'+'dal'='VANDAL'
Can you help me to learn more?
(Other definitions for vandal that I've seen before include "Cultural destroyer" , "Someone who wilfully damages property" , "Defacer or wrecker" , "One doing deliberate damage" , "One who wilfully defaces or destroys property" .)
