动摇 (dòngyáo) can mean both a physical shake (like wind shaking a tree) and a metaphorical destabilization (shaking confidence). Unlike physical-sway verbs like 摇摆/摇晃 (repetitive, self-initiated motion), 动摇 often implies a single disruptive jolt or a figurative weakening. In the metaphorical sense (wavering), 动摇 focuses on something being undermined or made unstable, while 犹豫不决/举棋不定 describe a person's hesitation in making a choice.
