Feature in West shows robot (7)
I believe the answer is:
machine
'robot' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'feature in west' is the wordplay.
'feature' becomes 'chin' (facial feature).
'in' is an insertion indicator.
'west' becomes 'mae' (actress Mae West).
'chin' put into 'mae' is 'MACHINE'.
'shows' is the link.
Can you help me to learn more?
(Other definitions for machine that I've seen before include "Mechanical or electrical device" , "Device providing energy to perform a task" , "Well-organised and powerful group" , "Device for work" , "Industrial worker" .)
