The kanji 貞 is a 会意文字 (かいいもじ), a compound ideogram, meaning it is formed by combining the meanings of existing characters. It is composed of two parts: the radical ト (占), which suggests divination or foretelling, and 貝 (かい), representing "shell" or "money." The combination of these suggests a woman's conduct that is determined by divination, thus emphasizing the importance of being faithful to a principle or the truth, and acting with moral integrity. The "shell" component implies something valuable that needs to be protected, much like a person’s virtue. This is also how we can derive the primary meanings of "chaste" or "virtuous."
