Person following vehicle reversing clipped kerb (7)
I believe the answer is:
tracker
'person' is the definition.
(I know that tracker is a type of hunter)
'following vehicle reversing clipped kerb' is the wordplay.
'following' means one lot of letters go next to another.
'vehicle' becomes 'cart' (cart is a kind of vehicle).
'reversing' says the letters should be written in reverse.
'clipped' means to remove the last letter (the word is shortened or clipped).
'cart' backwards is 'trac'.
'kerb' with its final letter taken away is 'ker'.
'trac' put next to 'ker' is 'TRACKER'.
(Other definitions for tracker that I've seen before include "fund" , "Rod in organ mechanism, trailer" , "One can follow" , "Investment" , "follower" .)
