The kanji 澪 is a phono-semantic compound (形声文字 - keisei moji). It is composed of two parts: the water radical 氵 (also written as 水 - mizu, meaning "water") on the left, and the phonetic component 余 (yo), which provides a sound clue for the reading. The combination suggests something related to water, with a sound association. This structure reflects how characters were formed by combining meaning and sound.
