Meaning & readings

star, spot, dot, mark

On’yomi セイ、ショウ
Kun’yomi ほし、-ぼし

Origin

The character combines two parts: the component , which represents the sun or a celestial body, and below it, which serves as a sound hint for pronunciation rather than contributing to the meaning. The upper part makes sense for a star since stars are bright objects in the sky like the sun. The lower component doesn't mean "life" or "birth" in this context—it's simply there to suggest how the character should be pronounced. Over time, this combination became the standard way to write the word for star in Japanese and Chinese.
