The kanji 噴 is a phono-semantic compound (形声文字, keisei moji). It combines the phonetic component 賁 (fun, meaning "to rush") with the radical 口 (kuchi, meaning "mouth"). The combination suggests something rushing out from the mouth (or a similar opening), thus conveying the meaning of "to spout" or "to erupt." 賁 originally depicted a person rushing towards something, suggesting the energetic or forceful aspect of the action. Over time, the meaning of 賁 shifted toward expressing something fast, and 口 was added to provide a more specific visual representation. This combination evolved to represent the act of something spewing forth.
