The kanji 菌きん is a 形声文字 (keisei moji), a phono-semantic compound. It is composed of the radical 艸 (くさかんむり, kusa kanmuri) on top, which signifies "grass" or "plants," and 畇 (kun), which provides the phonetic element. This suggests that the original meaning of 菌きん was related to something that grew like a plant, but was small and not visible to the naked eye. Over time, it came to represent fungi, bacteria, and germs. The shape of the kanji reflects the idea of small, often unseen organisms.
