The kanji 保 is a phono-semantic compound (形声文字 - keisei moji). The left side is the radical 亻 (ninben), which means "person." The right side is 呆 (bō), which represents "to be bewildered" or "to be in a daze." Originally, 呆 depicted a person in a daze or uncertain state. The addition of the "person" radical suggests someone protecting or safeguarding a person who is in such a vulnerable state, hence the meaning of "to protect" or "to keep." The formation suggests the early focus on providing security and support to those who need it.
