Follow us heading north in unspoiled surroundings (6)
I believe the answer is:
pursue
'follow' is the definition.
(to pursue is to follow or chase)
'us heading north in unspoiled surroundings' is the wordplay.
'heading north' is a reversal indicator (in a down clue, letters travel north).
'in unspoiled' becomes 'pure' (I've seen this in another clue. I am not sure about the 'in' bit.).
'surroundings' indicates putting letters inside.
'us' backwards is 'su'.
'su' put inside 'pure' is 'PURSUE'.
Can you help me to learn more?
(Other definitions for pursue that I've seen before include "Try to win" , "Engage in or chase after" , "Be engaged in - hunt" , "Follow up on or go after" , "Seek" .)
