The word "裹挟" is formed by combining the character "裹", meaning to wrap or envelop, which itself is composed of the radical "衣" (clothing) surrounding "果" (fruit), with the character "挟", meaning to coerce or force, composed of the radical "扌" (hand) and "夹" (to pinch). Together, these characters create a compound where the action of wrapping merges with forcing, resulting in the meaning of being swept along or involuntarily involved in something.
