View loch with small ness (9)
I believe the answer is:
landscape
'view' is the definition.
(natural view)
'loch with small ness' is the wordplay.
'loch' becomes 'l'.
'with' becomes 'and'.
'small' becomes 's' (abbreviation - e.g. clothes size).
'ness' becomes 'cape' (synonyms).
'l'+'and'+'s'+'cape'='LANDSCAPE'
(Other definitions for landscape that I've seen before include "Picture showing countryside" , "variety of shot" , "Artwork" , "The visible features of an area" , "Art of laying out scenic grounds" .)
