One suggesting to settle area away from the coast (10)
I believe the answer is:
hinterland
'area away from the coast' is the definition.
'one suggesting to settle' is the wordplay.
'one suggesting' becomes 'hinter' (someone who provides hints).
'to settle' becomes 'land'.
'hinter'+'land'='HINTERLAND'
(Other definitions for hinterland that I've seen before include "Remote inland areas" , "remote country region" , "Remote area of a country" , "Remote areas of a country" , "area around a port" .)
