Short cut round the far end (4)
I believe the answer is:
Here is my best explanation:
'short' is the definition.
('curt' can be a synonym of 'short')
'cut round the far end' is the subsidiary indication.
'cut' becomes 'cut' (**).
'round' indicates putting letters inside.
'end' says to take the final letters.
The final letter of 'far' is 'r'.
'cut' placed around 'r' is 'curt'.
(Other definitions for curt that I've seen before include "Brusque, short", "Dismissively short", "Brief and to the point", "Rude", "Discourteously brief", "Rudely abrupt, short", "Concise", "Rudely brief", "Short and abrupt" and "Terse and laconic".)
