The word **王妃 (wángfēi)** is a grammatically straightforward compound noun formed by combining the morpheme **王 (wáng)**, meaning "king" or "monarch," with the morpheme **妃 (fēi)**, meaning "imperial consort" or "royal concubine." It follows a modifier-head structure common in Chinese, where the first element **王** specifies the type or rank, acting as a genitive modifier ("of the king"), and the second element **妃** serves as the head noun, indicating the person's role. Thus, the compound directly and logically signifies "king's consort" or "queen consort," specifically the wife of a reigning king, rather than a ruling queen in her own right.
