Relating to or capable of breaking through or bursting outward from confinement.
From Latin ex- 'out' + rumpere 'to break, burst.' A rare or archaic term for something that breaks or erupts outward, potentially describing volcanic or biological phenomena.
Exrupeal is a word so obscure that even comprehensive dictionaries barely acknowledge it—it seems designed to describe something breaking out, but 'eruptive' does the job better and actually gets used.
