precious, value, prize, esteem, honor
貴 centers on high worth and the respect it commands: something precious, valued, or honored. The ideas of prize and esteem are natural extensions of that same sense of elevated value.
貴 combines 貝 (shell, representing value or money) with a phonetic element that also suggests a basket or container, giving the idea of something valuable and worthy of respect.
The bottom is 貝 (shell, an old form of currency), and the top looks like a basket holding something precious. Picture a basket full of valuable shells, something to be esteemed and honored.
For キ, imagine a precious key unlocking a treasure chest: key -> キ, and the treasure inside is highly valued.
