Gives a start to vehicle impounded by State Emergency Service (6)
I believe the answer is:
scares
'gives a start to' is the definition.
(I've seen this in another clue)
'vehicle impounded by state emergency service' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'impounded by' indicates putting letters inside.
'state emergency service' becomes 'ses' (this might be a standard abbreviation of which I'm unaware).
'car' inserted within 'ses' is 'SCARES'.
Can you help me to learn more?
(Other definitions for scares that I've seen before include "Affrights" , "Frightens or intimidates" , "Terrifies" , "Alarms" , "Causes fear" .)
