Definizione monolingua

knot

knot (third-person singular simple present knots, present participle knotting, simple past and past participle knotted)

1. To form into a knot; tie with (a) knot(s).

2. To form wrinkles in the forehead, as a sign of concentration, concern, surprise, etc.

knot (plural knots)

1. A looping of a piece of string or of any other long, flexible material that cannot be untangled without passing one or both ends of the material through its loops.

   Climbers must make sure that all knots are both secure and of types that will not weaken the rope.

2. (of hair, etc) A tangled clump.

   The nurse was brushing knots from the protesting childs hair.

3. A maze-like pattern.
4. (mathematics) A non-self-intersecting closed curve in (e.g., three-dimensional) space that is an abstraction of a knot (in sense 1 above).

   A knot can be defined as a non-self-intersecting broken line whose endpoints coincide: when such a knot is constrained to lie in a plane, then it is simply a polygon.

       A knot in its original sense can be modeled as a mathematical knot (or link) as follows: if the knot is made with a single piece of rope, then abstract the shape of that rope and then extend the working end to merge it with the standing end, yielding a mathematical knot. If the knot is attached to a metal ring, then that metal ring can be modeled as a trivial knot and the pair of knots become a link. If more than one mathematical knot (or link) can be thus obtained, then the simplest one (avoiding detours) is probably the one which one would want.

5. A difficult situation.

   I got into a knot when I inadvertently insulted the policeman.

6. Either of two species of small wading birds, the red knot (Calidris canutus) and the great knot (Calidris tenuirostris).
7. The whorl left in lumber by the base of a branch growing out of the trees trunk.

8. Local swelling in a tissue area, especially skin, often due to injury.

9. A group of people or things.
   • 1968, Bryce Walton, Harpoon Gunner, Thomas Y. Crowell Company, NY, (1968), page 20,

     He pushed through knots of whalemen grouped with their families and friends, and surrounded by piles of luggage.
