Scour the bush country (5)
I believe the answer is:
scrub
This could be a double definition.
'scour' is the first definition.
(I know that scour can be written as scrub)
'bush country' is the second definition.
'scrub' can be an answer for 'bush' (thesaurus). I am not sure about the 'country' bit.
'the' is the link.
Can you help me to learn more?
(Other definitions for scrub that I've seen before include "Get rid of" , "plants" , "Powerful wash" , "Rub hard; brushwood" , "Scour - stunted trees" .)
