The Chinese word "充电" is formed by directly combining the character "充", which conveys the action of filling or supplying, with the character "电", which represents electricity. This juxtaposition creates a compound that literally means "to charge electricity", visually and conceptually capturing the process of replenishing electrical energy in a device. The formation relies on the intuitive pairing of an action with its target, resulting in a term that is transparent in meaning from its components, exemplifying how Chinese often constructs words through descriptive, concept-driven combinations.
