The word **夸大** is formed through a typical Chinese morphological process called **compounding**, where two independent characters, each with their own meaning, are combined to create a new, related semantic unit. The first character, **夸** (*kuā*), carries the core meaning of "to boast" or "to praise," while the second, **大** (*dà*), means "big" or "large." When combined, they create a verb meaning "to exaggerate" or "to overstate," literally conveying the idea of "making (something) big through boasting," where the action of **夸** is applied to the state of **大**, resulting in an amplified or inflated description beyond the facts.
