The kanji 胞 is a phono-semantic compound. The phonetic component is 包 (hō), meaning "to wrap" or "to envelop," and the semantic component is 月 (tsuki/getsu), which, when used as a radical on the left side, is a variation of the radical 肉 (niku) which means "flesh" or "body." This combination suggests something wrapped or contained within the body, which perfectly reflects its meaning of "cell," "sac," or "capsule." The 包 indicates the enveloping function, and the 肉 relates to the biological context. The historical development shows the evolution from pictograms to a more abstract form as writing developed.
