The kanji 垣 is a phono-semantic compound (形声文字). The left side is 土 (つち - soil/earth), which acts as the semantic component, indicating that the character relates to something made of earth or is related to land. The right side is 亘 (わたる - to extend/span), which is the phonetic component, providing the sound and suggesting the idea of extending or spanning to create a barrier. Therefore, the character combines the idea of earth (related to the material) with the sound and the idea of creating an extending boundary. The historical development shows that the basic form of the kanji has remained fairly consistent over time, emphasizing its connection to the physical construction of a barrier.
