Sheepshank or bowline? (4)
I believe the answer is:
knot
I believe this clue is a double definition.
'sheepshank' is the first definition.
(I've seen this in another clue)
'bowline?' is the second definition.
(bowline is a kind of knot)
(Other definitions for knot that I've seen before include "A sheepshank or bowline" , "Eskimo people" , "Measure of speed at sea" , "Bird; speed; tie" , "binder?" .)
