The Chinese word **贞洁** (zhēnjié) is a compound term formed by combining two characters with related meanings: **贞** (zhēn), which historically conveys notions of moral uprightness, constancy, and loyalty (particularly in terms of chastity or fidelity), and **洁** (jié), which means pure, clean, or untainted. Together, they create a single, reinforced concept meaning **chastity** or **moral purity**, where "贞" emphasizes the ethical aspect of faithfulness and integrity, and "洁" emphasizes the spotless, uncorrupted quality, resulting in a term that specifically denotes sexual purity and virtuous conduct.
