About
The character 孛 (bèi) is composed of 十, 冖, and 子 in its modern form. Its etymology traces back to the image of plants sprouting or thriving suddenly, a concept later extended to sudden celestial appearances like comets, historically called 孛星 (bèixīng, "bushy star"). Over time, its meaning shifted from rapid vegetation growth to describe abrupt changes in general, such as unexpected facial expressions or astronomical events. The lower component 子 (child or seed) retains the foundational link to seeds sprouting, even as the character's usage broadened to emphasize suddenness and cosmic anomalies.
