Provide machinery for chum getting under car (8)
I believe the answer is:
automate
'provide machinery' is the definition.
'chum getting under car' is the wordplay.
'chum' becomes 'mate' (I've seen this before).
'getting' is a charade indicator (letters next to each other).
'under car' becomes 'auto' ('auto' can be a synonym of 'car'. I am not sure about the 'under' bit.**).
'mate' after 'auto' is 'AUTOMATE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for automate that I've seen before include "Cause to function without direct human control" , "Mechanise to make something work without human intervention" , "Take the manual out of" , "No longer employ person" , "Eat out ma - make it self-regulating" .)
