A more formal or literary way to say 'lose one's composure'. 平静 means calmness or serenity.

When someone's composure cracks in a social or high-pressure situation, often with embarrassment.
Also used here; emphasizes the visible loss of control, like crying or shouting.

動揺する is an internal feeling of being shaken, while 取り乱す implies outward signs like crying, shouting, or disorganized behavior. Use 動揺する for a quieter loss of composure, and 取り乱す when it's clearly visible.

彼は厳しい指摘にたじろいだ。
He lost his composure at the harsh criticism.
