Origin

The character combines the flesh or body radical () on the left, which classifies this as a word about the physical body, with a sound hint (巴) on the right that suggests the "hi" pronunciation. The meaning evolved from describing the body becoming large or fat, to fertilizer that makes plants grow fat and fertile, then to the act of fattening or enriching soil. The connection between body fat and fertilizer both involve growth and richness, which is why this single character carries meanings ranging from personal weight gain to agricultural fertility.
