The word 疗法 is formed by combining two meaningful characters: 疗 (liáo), which carries the core idea of "to treat" or "therapy", and 法 (fǎ), which means "method" or "way". Their conceptual fusion is direct and intuitive; the first character provides the substantive field (medical treatment), and the second character specifies the form or approach within that field. Thus, the compound naturally synthesizes into the concept of a "therapeutic method" or a specific "course of treatment", where the whole meaning is essentially the sum of its transparent parts.
