The Chinese word **懒惰 (lǎnduò)**, meaning "lazy" or "slothful," is a typical example of a disyllabic compound formed through **synonym pairing**, where two characters with similar meanings are combined to create a single, reinforced concept. The first character, **懒 (lǎn)**, directly means "lazy" or "indolent," while the second, **惰 (duò)**, conveys "idle," "inert," or "sluggish." By joining these two semantically related morphemes, the compound word **懒惰** achieves a more emphatic and nuanced expression of the idea of laziness than either character could convey alone, which is a fundamental and common method of word formation in modern Chinese.
