Etymology
Irruptive comes from Latin parts in- meaning 'into' and rumpere meaning 'to break', and it is related to English words like erupt and rupture. For igneous rocks, imagine hot melted rock pushing into the earth and then cooling underground, so irruptive describes rocks formed when magma breaks in and cools below the surface.
