accumulate, involvement, trouble, tie up, continually
累 centers on things piling up or becoming entangled: accumulating over time, getting tied up in involvement, or facing trouble that builds from repeated small issues.
累 combines 田 (field) and 糸 (thread), originally depicting threads piled up or entangled in a field, conveying accumulation and involvement.
Picture threads 糸 piling up in a field 田, getting tangled and accumulating until they become a troublesome knot.
For ルイ, imagine a ruined field where threads have accumulated into a huge tangled mess: ruined -> ルイ.
