The kanji 杜 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is 木 (ki), meaning "tree," and the right side is 土 (tsuchi), meaning "earth" or "ground." The character combines the meaning of "tree" with "earth/ground," suggesting a place where trees grow in the earth, such as a grove or woods. Over time, the character evolved to encompass a more general meaning of "woods."
