The Chinese word **肺癌 (fèi'ái)**, meaning "lung cancer," is formed through a straightforward compound morphological process common in the language. It combines the first character **肺 (fèi)**, which means "lung," with the second character **癌 (ái)**, which means "cancer." This creates an endocentric compound noun where the first element specifies the location or type of the second, general element, resulting in a precise, semantically transparent term for a disease affecting a specific organ.
