Short stretch of intersection (5)
I believe the answer is:
terse
'short' is the definition.
(terse can mean short or brusque)
'stretch of intersection' is the wordplay.
'stretch of' says the answer is hidden in the clue (a stretch of letters from the clue).
'TERSE' is hidden in the letters of 'intersection'.
(Other definitions for terse that I've seen before include "Reset to be pithy" , "Brief and to the point" , "Curt - abrupt" , "Briefly expressed" , "Short, abrupt" .)
