The word 无法 is formed by combining the character 无, meaning "without" or "to lack", with the character 法, whose core meaning is "method", "way", or "standard". It is a conceptual fusion where the state of absence (无) is directly applied to the means or possibility (法), creating a single unit that conveys the abstract idea of "having no way to" or "being unable to". This is not a temporary phrase but a fixed, lexicalized compound where the two characters have merged to express a unified concept of impossibility or incapacity.
