The kanji 揺 represents the action or state of "shaking," "swinging," "swaying," or "vibrating." It conveys the idea of something moving back and forth or up and down, often in a gentle or rhythmic manner, but can also imply a forceful or uncontrolled movement. This can apply to physical objects, emotions, or even abstract concepts like opinions.

The kanji 揺 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is a radical, and the right side acts as a phonetic component. The left radical is 扌 (てhen, tehen), which means "hand." It signifies that the character is related to hand actions or movements. The right side is 䍃 (よう, yō), which is the phonetic component, suggesting the sound and perhaps contributing to the original meaning of swinging or swaying. Thus, the kanji 揺 originally depicted the movement of something caused by a hand. Over time, the meaning broadened to encompass any kind of shaking or swaying motion.
