Origin

This character combines the radical for earth or soil on the left with a sound component on the right that suggests the pronunciation. The left side, a simple square representing soil or ground, establishes the basic meaning — this character is about earth or soil. The right component is primarily there to hint at how the word should sound rather than to add meaning. Together they create a character that specifically refers to soil or earth in the sense of ground or a plot of land, building on the visual concept of soil while signaling its spoken form.
