The kanji 胞 is a 形声文字 (keisei moji), a phono-semantic compound. It is composed of the radical 月 (にくづき), which represents "flesh" or "body" and the phonetic component 包 (hou), which conveys the sound and provides a clue to the meaning, as 包 means "to wrap" or "to enclose." The combination suggests something that encloses or contains something within the body. The evolution of the character shows that it was originally related to the concept of something enclosed within the body.
