The word 数量 is formed through the conceptual combination of two independent characters, each representing a core idea related to measurement. The first character, 数 (shù), fundamentally conveys the idea of counting, numbers, or enumeration. The second character, 量 (liàng), carries the meaning of measuring, capacity, or magnitude. When combined, they create a composite concept that merges the act of counting discrete units (数) with the act of assessing continuous extent or volume (量), resulting in the integrated meaning of "quantity" or "amount".
