Car in cemetery tries heading for exit (6)
I believe the answer is:
hearse
'car in cemetery' is the definition.
'hearse' can be an answer for 'car' (hearse is a kind of car). I'm not sure about the 'in cemetery' bit.
'tries heading for exit' is the wordplay.
'tries' becomes 'hears' (as in trying or hearing in a trial).
'heading for' suggests taking the first letters.
The first letter of 'exit' is 'e'.
'hears'+'e'='HEARSE'
Can you help me to learn more?
(Other definitions for hearse that I've seen before include "Last time transport" , "Undertaker's car" , "Carriage for a coffin" , "Vehicle bearing coffin" , "Funeral carriage" .)
