noun / verb
knot
NAHT/nɑːt/
A tight tangle formed by interlacing flexible strands.

Etymology
Old English cnotta already named an intertwining of ropes or cords. The modern fastening sense preserves that concrete idea: strands interlaced to form a tied whole.
In context
just tighten that up into a really tight knot and nothing will happen what you've got to do is you've got to just take that out of the loop
