The word 包裹 is formed by combining two characters, 包 and 裹, which both individually convey the core idea of wrapping. 包 primarily means "to wrap", "to enclose", or "a bundle", often visualized as something contained within a parcel. 裹 means "to bind", "to swathe", or "to wrap up", emphasizing the action of surrounding an object completely. When placed together, they create a compound that reinforces and specifies the concept, resulting in the meaning of a "package" or "parcel", an item that has been thoroughly wrapped and bound for carrying or sending.
