乱 uses the radical 乙, often seen in complex or abstract characters. The full kanji depicts tangled threads — symbolic of disorder or being out of control. It’s often used in political, social, or emotional contexts to indicate chaos or conflict.

The old form, 亂らん, includes a visual component representing twisted threads and voices — further reinforcing the meaning of turmoil.

彼かれの 行動こうどうは 乱暴らんぼうすぎる。
His behavior is too violent.

戦争せんそうの 影響えいきょうで 国内こくないは 混乱こんらんしている。
The country is in chaos due to the effects of war.

“らん” is the most common reading in compound words.
As a verb, it appears in forms like “みだれる” (to be disordered) and “みだす” (to throw into disorder).
