🗺️ 地域 = land + domain — a bounded stretch of territory
域 means bounded space and shows up in 区域 (region) and 领域 (field/domain). Paired with 地 (land/ground), it marks out a specific tract or quarter on the map.
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.'
