A partially coiled rope is found inside (6)
I believe the answer is:
lariat
'a partially coiled rope' is the definition.
'lariat' can be an answer for 'rope' (lariat is a kind of rope). I'm not sure about the 'a partially coiled' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for lariat that I've seen before include "Rope with running loop at one end" , "A cowboy's working rope" , "Tethering rope" , "Long rope with a noose at the end" , "Cattle-catching rope" .)
