happiness, blessed, good fortune, auspicious
禎 centers on positive, fortunate outcomes: happiness, blessings, good fortune, and auspicious signs. It describes a state of being favored by luck or divine goodwill.
禎 combines 示 (altar, divine) with 貞, which likely contributes the sound and carries a sense of correctness or uprightness, together suggesting divine favor or auspiciousness.
The left side 示 (礻) represents an altar or divine presence. The right side 貞 looks like a person standing upright under a roof, suggesting correctness. Picture a divine blessing descending upon an upright person at an altar, bringing happiness and good fortune.
For テイ, imagine a tea ceremony (ティー) held at the altar to celebrate a blessing: tea -> テイ, and the ceremony brings happiness and good fortune.
