Short cut round the far end (4)
I believe the answer is:
curt
'short' is the definition.
(impolite)
'cut round the far end' is the wordplay.
'round' is an insertion indicator.
'end' says to take the final letters.
The final letter of 'far' is 'r'.
'cut' enclosing 'r' is 'CURT'.
(Other definitions for curt that I've seen before include "Concise" , "Brusquely succinct" , "Rudely abrupt, short" , "Brief and terse" , "Rude" .)
