乱れる
みだれる
- middle-high (nakadaka): falls after mora 3
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
to get confused, to be disordered, to be disturbed
Midareru is from Old Japanese, from Proto-Japonic, and is compared with みだら (midara, “obscene, indecent”) and 乱す (midasu, “to disturb”).
