The kanji 藻 is a phono-semantic compound (形声文字). The left side is the radical 艹 (くさかんむり - kusakanmuri), which signifies "grass" or "plants," indicating the character's association with plant life. The right side is 藻 (そ - so), which functions as the phonetic component, suggesting the sound and also contributing to the meaning. Together, these components create a character that specifically refers to aquatic plants such as seaweed and algae.
