Meaning & readings

vice-, assistant, aide, duplicate, copy

On’yomi フク
Nanori そい、そえ

Origin

The character 副 combines a sound hint on the left with a knife radical on the right. The left component 畐 doesn't contribute to the meaning but signals roughly how the character should sound. The knife radical 刂 on the right suggests the idea of cutting or dividing something into parts. Together, these components convey the sense of something that is cut away or separated—a secondary or auxiliary thing, like an assistant or duplicate that exists alongside something main. This visual logic captures how the character came to mean "vice-" or "assistant."
