Point, or points, one repeated (4)
I believe the answer is:
ness
'point' is the definition.
(I've seen this in other clues)
'points one repeated' is the wordplay.
'points' becomes 'NEs' (NE is an example).
'one repeated' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'nes'+'s'='NESS'
'or' acts as a link.
Can you help me to learn more?
(Other definitions for ness that I've seen before include "Scottish lake with traditional monster" , "Scottish Loch famed for monster" , "head" , "Eliot -, led effort against Al Capone; Scots loch" , "Scottish loch - headland" .)
