E‐rupt″ (?), v. i. [See Eruption.] 1. To eject something, esp. lava, water, etc., as a volcano or geyser.
2. To burst forth; to break out, as ashes from a volcano, teeth through the gums, etc.
When the amount and power of the steam is equal to the demand, it erupts with violence through the lava flood and gives us a small volcano. H. J. W. Dam.
