The word 无数 is formed through a direct and vivid conceptual combination: the first character 无 (wú) means "without" or "there is no", and the second character 数 (shù) means "number" or "count". When fused, they create a single idea that transcends the simple sum of its parts, it evokes the image of an amount so vast, limitless, or chaotic that it escapes enumeration, conceptually picturing a realm "beyond number". This formation captures an abstract quality of immeasurability by literally stating the absence of the very possibility of counting.
