This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development is uncertain. The modern form visually contains 糸 (thread) and 纍, but the original component relationships are unclear.
The kanji is made of thread 糸 and a complex right side 纍. Without a clear meaning, picture a tangled mass of threads that is hard to unravel.
For ルイ, imagine a tangled thread that looks like a ruined mess: ruined -> ルイ, and the threads are hopelessly knotted.
