Meaning & readings

sponsor, hold (a meeting), give (a dinner)

On’yomi サイ
Kun’yomi もよう.す、もよお.す

Origin

The left component, a person radical, shows this character relates to human action or gathering. The right side, which sounds like "sai," serves as a sound hint to indicate how the character is pronounced. When you combine a person doing something with the sound indicator for sai, you get a character meaning to sponsor or organize — essentially, a person bringing others together for an event like a meeting or dinner. Over time, the specific sense narrowed to actions like holding or sponsoring such gatherings.
