The kanji 築 is a phono-semantic compound (形声文字, keisei moji). It is composed of two parts: The left side is the radical 土 (つち, tsuchi), meaning "earth" or "ground", it provides the meaning. The right side is the phonetic 筑 (チク, chiku), which gives a clue to the pronunciation. The combination suggests the act of building something on the earth, building a solid structure. The original meaning of 筑 was related to the construction of earthen structures and foundations. Over time, it came to be used more broadly for any kind of construction.
