Origin of the Earth’s Kanji 土

In the olden days, farming was the most fundamental primary occupation for human beings. So, from the eyes of early human beings, the earth or ground was a significant life support, and it was very natural to visualize and connect the earth with farming activities.

Now, if you visualize a person plowing the farm, you can’t ignore the image of earth mounds or heaped piles of earth. The following picture explains it:

The Kanji of Earth originally depicted a lump of earth or a pile of dirt. Over time, it was simplified and standardized into the character we see today as 土.

土 as a Radical and Component in other Kanji Characters

The character 土 also appears as a Kanji radical. Some of the names for the radicals of the kanji 土 are as follows:

  1. “つちへん” (tsuchihen) or どへん” (dohen): A radical when 土 appears at the left-hand side of the kanji.
  2. “つち” (tsuchi): This name is for the radical of Earth’s Kanji regardless of its position.

Overall, Kanji 土 appears as a radical or as a component in 1380 Kanji characters, including 226 Jōyō Kanji.

Examples of Kanji 土 as a radical

Following are some examples of kanji where 土 (ground/earth) appears as a radical:

  • 坂 (saka, meaning “slope”): This kanji combines 土 with 反. The character 反 originally meant a “rebellion” or “contrary action” and might here suggest an incline going “against” the natural level of the ground.
  • 城 (shiro, meaning “castle”): Here, 土 is combined with 成 (become or turn into). So the combination of “earth” and “turn into” suggests the construction of fortifications in the ground.
  • 地 (chi, meaning “land” or “earth”): This character combines 土 with 也. The character 也 on its own doesn’t have a clear meaning but is used in various characters with a phonetic function.
  • 園 (en, meaning “garden”): 土 is combined with 袁. The character 袁 originally represented a long robe, suggesting an area of ground as expansive as a robe is long.
  • 均 (kin, meaning “equal”): The Kanji combines 土 with 勹 (wrap), suggesting the idea of parcels of land being divided evenly.
  • 場 (ba, or “jou” meaning “place” or “location”): Combines 土 with 昜, a pictograph of the sun rising above the horizon, suggesting a broad, open place.
  • 塩 (shio, meaning “salt”): The kanji combines 土 with 兼. The character 兼 means “concurrently,” possibly representing salt obtained from the earth.
  • 培 (bae, meaning “cultivate”): This kanji pairs 土 with 咅, which is thought to represent a mouth expelling breath, signifying the process of tilling or cultivating the soil.
  • 堕 (da, meaning “degenerate”): This kanji combines 土 with 陏. It implies the process of falling or degradation, like something falling to the ground.
  • 坑 (kou, meaning “pit”): Combines 土 with 工, which means “work,” suggesting the act of digging a hole or a pit in the ground.
