An outstanding part of the country (4)
I believe the answer is:
ness
This could be a double definition.
'an outstanding part' is the first definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'country' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'of the' is the link.
Can you help me to learn more?
(Other definitions for ness that I've seen before include "head" , "Loch in the Great Glen" , "Headland, promontory" , "Scottish Loch famed for monster" , "Eliot -, led effort against Al Capone; Scots loch" .)
