Method for scrapping upturned vehicle, running a trial (7,3)
I believe the answer is:
martial art
'method for scrapping' is the definition.
I can't judge whether this definition defines the answer.
'upturned vehicle running a trial' is the wordplay.
'upturned' says the letters should be written in reverse.
'vehicle' becomes 'tram' (tram is a kind of vehicle).
'running' indicates anagramming the letters (the letters run around to different places).
'tram' backwards is 'mart'.
'a'+'trial'='atrial'
'atrial' anagrammed gives 'ialart'.
'mart'+'ialart'='MARTIAL ART'
Can you help me to learn more?
(Other definitions for martial art that I've seen before include "for which war paint could be used?" , "Combat technique" , "As a form of self-defence" , "the construction of epigrams?" , "Skilled defence" .)
