war, disorder, riot, disturb
亂 centers on a state of violent upheaval and confusion: war, disorder, and riot. It also covers the act of disturbing or throwing things into chaos.
亂 is the traditional form of 乱. The left side is complex and likely depicts tangled threads or a disordered scene, while the right side 乚 may represent a tool or action that separates or controls. The overall idea is disorder or the act of bringing order to chaos.
The tangled, chaotic left side looks like a mess of threads and claws, while the right side 乚 is a hook trying to pull them apart. Imagine a riot of tangled strings being disturbed and pulled into war.
For ラン, picture a chaotic battlefield where soldiers run in disorder: run -> ラン, and the scene is one of war and riot.
