The kanji 噴 (fun) fundamentally means "to spout," "to erupt," "to spew," or "to gush out." It implies a forceful release of something, often a liquid or a gas, from a confined space or source. This release is usually sudden and visible.

The kanji 噴 is a phono-semantic compound (形声文字). The left side is the radical 口 (kuchi), meaning "mouth." The right side is the phonetic component 賁 (hon), which provides the sound and the original meaning of "to rush forward" or "to burst forth." The combination of 口 and 賁 suggests the idea of something bursting forth from a mouth, leading to the meaning of "to spout" or "to erupt."
