Scenery of country's headland (9)
I believe the answer is:
landscape
'scenery' is the definition.
(I know that landscape is a type of scenery)
'country's headland' is the wordplay.
'country's' becomes 'land's' ('land' can be a synonym of 'country').
'headland' becomes 'cape' (I've seen this in another clue).
'lands'+'cape'='LANDSCAPE'
'of' acts as a link.
(Other definitions for landscape that I've seen before include "Artistic work" , "Piece of inland scenery" , "Picture showing countryside" , "Broad view of scenery" , "Artwork" .)
