Bowline or sheet bend? (4)
I believe the answer is:
knot
I believe this is a double definition.
'bowline' is the first definition.
(I've seen this in another clue)
'sheet bend?' is the second definition.
(sheet bend is a kind of knot)
(Other definitions for knot that I've seen before include "A sheepshank or bowline" , "one may find in wood" , "Sort of garden" , "Eskimo people" , "Difficult problem" .)
