rope
繘 centers on a rope, specifically a well rope used for drawing water. The meaning is narrow and concrete, referring to the cord itself.
繘 combines 糸 (thread) with 矞, which likely contributes the sound. The character is used for a well rope, but the exact historical development of 矞 is uncertain.
The left side 糸 is thread, and the right side 矞 looks like a complex mechanism. Picture a strong rope made of many threads wound around a well pulley: 繘 is the rope that draws water.
For キツ, imagine a well rope that is so tight it makes a 'kits' sound when pulled: kits -> キツ, and the rope is taut.
