Etymology

kanji roots 乱 denotes chaos or disorder, and す is the native verb ending that converts the noun/root into the action of causing that state.

Composition

  • 乱: chaos, disorder — the core meaning
  • す: native verb ending that attaches to a stem to form the verb

Usage

Used in formal and everyday contexts as a transitive verb that takes を after a noun to express causing disorder; common collocations include 秩序を乱す, 平穏を乱す, 計画を乱す, 心を乱す in literary or expressive writing.
💡 Tips
Mnemonic: visualize the kanji 乱 as a jumble of people creating chaos, then imagine adding す as the action that turns chaos into an intentional act—乱す means to cause disorder.
