Artist set up part of vehicle (6)
I believe the answer is:
radial
'part of vehicle' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'artist set up' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'set' becomes 'laid' (synonyms).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'laid' backwards is 'dial'.
'ra'+'dial'='RADIAL'
Can you help me to learn more?
(Other definitions for radial that I've seen before include "tire (American)" , "Sort of tyre" , "With lines or spokes from a central point" , "a sort of drill" , "Diverging from a common centre" .)
