Noosed rope (5)
I believe the answer is:
lasso
'noosed rope' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lasso that I've seen before include "Cow catcher" , "Rope with noose for catching animals" , "something to catch beast liable to run off" , "Long-noosed rope" , "Ling-nosed rope" .)
