UK: ɪˈrʌpʃən | US: ɪˈrʌpʃən
n. a sudden, violent outburst (e.g., of a volcano, emotion, or conflict)

n. (medicine) the appearance of a rash or lesion on the skin
The word "eruption" derives from Latin eruptio, from erumpere ("to break out"), combining e- (meaning "out") and rumpere ("to break"). The root rupt appears in many English words (e.g., "rupture," "interrupt"), reflecting the idea of forceful breaking or bursting. Over time, "eruption" expanded from literal volcanic bursts to metaphorical outbursts (e.g., emotions, protests). The suffix -ion standardizes it as a noun denoting action or result.
