The word 容易 is formed through the conceptual combination of its two component characters: 容, which carries meanings of "to contain", "to allow", or "appearance", and 易, which means "to change" or "exchange". When joined, they create an abstract idea where 容 suggests a state of accommodation or lack of resistance, and 易 implies something that can be altered or handled without difficulty. This fusion metaphorically paints a picture of a situation or task that is "accommodating to change", ultimately yielding the modern meaning of "easy" or "likely".
