The Chinese word 简短 (jiǎnduǎn) is a compound adjective formed by combining two characters with closely related meanings to reinforce a single concept. The first character, 简 (jiǎn), conveys "simple", "concise", or "brief", while the second character, 短 (duǎn), means "short" in terms of length or duration. By pairing these two synonyms, the compound word 简短 emphasizes the idea of being both brief in form and concise in content, essentially meaning "short and to the point". This is a common pattern in Chinese morphology where two characters of similar meaning are combined to create a nuanced or emphatic term.
