tie
縲 centers on binding or tying with cord or thread, often in a restrictive or confining sense.
縲 combines 糸 (thread) with 累 (accumulate, involve), likely functioning as a phono-semantic compound where 累 hints at the sound and the idea of entanglement or binding.
Thread 糸 on the left and 累 (accumulate) on the right suggest piling up thread to tie something securely.
For ルイ, imagine tying a knot so tight it looks like a Louis Vuitton logo: Louis -> ルイ, and the thread binds everything together.
