land
🌍 地 = earth + 盤 = plate: earth as a flat plate, so 地盤 = the ground
地 means earth and 盤 means plate or tray. Together they name the solid ground that a building or structure rests on.
地 — earth 土 + 也 (phonetic)
地 is a semantic-phonetic compound. The left component 土 means 'earth' or 'soil' and gives the meaning, while 也 on the right hints at the pronunciation. Originally referring to the ground or land, it broadened to mean 'place,' 'region,' and 'territory.'
