upright, chastity, constancy, righteousness
貞 centers on moral firmness and unwavering principle: being upright, righteous, and constant in character. Chastity is a specific application of that same steadfast purity.
貞 combines ⺊ (divination) and 貝 (shell, value). The original sense likely involved divination to determine what is correct or constant, later extended to moral uprightness.
A divination tool ⺊ over a precious shell 貝 suggests seeking a true, unchanging answer. Picture a priest consulting an oracle to confirm what is right and constant: that is uprightness.
For テイ, imagine a tea ceremony where every movement is upright and precise: tea -> テイ, and the ceremony embodies constancy and righteousness.
