The Chinese term for "appendix" (the organ), **阑尾 (lánwěi)**, is a straightforward compound word formed by combining two meaningful characters: **阑 (lán)**, which carries connotations of "late," "final," or "the end of something," and **尾 (wěi)**, which literally means "tail." Therefore, the term is a direct semantic description of the anatomy—it refers to the "final tail" or "blind end" of the cecum (the beginning of the large intestine), which is precisely what the vermiform appendix is. This formation is typical of Chinese medical terminology, where words are often built logically from descriptive roots to name anatomical parts.
