“knot” vs. “not”
Use "knot" for a tied fastening, tangle, or nautical speed unit; use "not" for negation.
knot
"Knot" is a noun for a fastening made by looping and tightening rope, string, or thread, and also a nautical unit of speed equal to one nautical mile per hour ("tie a knot," "the ship sailed at twenty knots"). It comes from Old English "cnotta," a Germanic word for a tied loop, and the speed sense derives from sailors historically measuring speed using knotted rope.
not
"Not" is an adverb used to negate or deny a statement ("I am not going," "that is not correct"). It comes from Old English "nawiht," a contraction of "na" (no) and "wiht" (thing/creature), literally meaning "no thing" — one of the most fundamental negation words in the language.
The real distinction
On paper the two look almost interchangeable, but one names a physical fastening or a speed unit while the other is simply a basic word of negation used constantly in every kind of sentence. "Knot" always describes something tied, tangled, or a specific measurement of nautical speed (a boat traveling at fifteen knots). "Not" is a grammatical function word that simply denies or negates whatever follows it. If your sentence involves rope, tangled hair, tension ("a knot in her stomach"), or nautical speed, use "knot"; in every other case where you're negating a statement, use "not." The silent "k" in "knot," like in "knight" and "knead," is a leftover from a time when it was actually pronounced. Sailing, climbing, and scouting manuals depend on precise knot terminology — bowline, clove hitch, square knot — each naming a specific technique, while "not" simply negates whatever statement surrounds it in ordinary prose. If your sentence involves rope, tension, or nautical speed, reach for "knot"; everywhere else, especially when denying or refusing something, "not" is what you need.

Memory trick
"Knot" keeps the same silent "k" pattern as "knee" and "knife" — old Germanic words for physical things you can touch. "Not" has no hidden letters at all, just a plain, simple word for denying something. Rope, tension, or nautical speed calls for the silent-k spelling; a plain denial never needs one.
