The kanji 泥 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of two parts: the semantic component 氵 (san-zui, meaning "water") and the phonetic component 尼 (ni, which suggests the sound). The presence of 氵 indicates its connection to water or a wet substance, while 尼 provides a clue to the pronunciation. Historically, the character's form has remained relatively consistent, reflecting the fundamental association with muddy or dirty substances.
