The word 大量 is formed by the direct combination of two independent characters: 大 (dà), meaning "big" or "great", and 量 (liàng), meaning "quantity" or "amount". They are placed side-by-side in a simple, semantic compound structure where the first character 大 descriptively modifies the second character 量, conceptually merging to create the combined meaning of "a large amount" or "great quantity". This formation is a straightforward fusion of two core ideas into a single, consolidated concept.
