The kanji 堤 堤 is a phono-semantic compound (形声文字, けいせいもじ). The left side of the character is the radical 土 (tsuchi), meaning "earth" or "soil," indicating that it relates to something made of earth. The right side of the character is 是 (ze), which originally functioned as a phonetic component. This means the sound of the word "ze" was used to help determine how the kanji should be pronounced. It now generally means "this". Therefore, the combination suggests the building of an earth structure and how the sound "ze" was pronounced at the time. Over time, the meaning of "bank" or "dike" evolved to become the primary meaning.
