The kanji 城 is a pictophonetic compound (形声文字). It is composed of two parts: 土 (tsuchi, meaning "earth" or "ground") and 成 (sei/naru, meaning "to become" or "to form"). The 土 radical indicates the building material of the castle, while 成 contributes to the sound and suggests the idea of "becoming" or "being constructed." The character originally depicted a walled-in area, gradually evolving into its current form to represent a fortified structure. The structure itself is built on 土 (earth).
