The Chinese word 寒冷 (hánlěng) is a binome compound formed by combining two independent, synonymous characters: 寒 (hán), which means "chilly" or "frigid" (often implying a severe, penetrating cold), and 冷 (lěng), which means "cold" in a general or sensory sense. This pairing follows a common pattern in Chinese morphology where two characters of similar meaning are joined to create a single, more emphatic or formal term. The result is a word that comprehensively conveys the concept of "coldness", blending the nuanced intensity of 寒 with the direct sensation of 冷 to describe bitterly low temperatures.
