Race towards animal park on motorway (4)
I believe the answer is:
zoom
'race' is the definition.
(both can mean to move quickly)
'animal park on motorway' is the wordplay.
'animal park' becomes 'zoo' (I've seen this in another clue).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'motorway' becomes 'M' (as in motorway names - M1, M4 etc).
'zoo'+'m'='ZOOM'
'towards' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for zoom that I've seen before include "go very fast" , "Lens to move into a close-up" , "Change from long shot to close-up or vice versa" , "Whizz - camera lens" , "cinematic technique?" .)
