Morphology

irruptive = irrupt (semi-transparent) = irrupt + ive

Formed regularly from the verb 'irrupt' + '-ive', but 'irrupt' is rare and the geological sense is technical so the meaning is not fully predictable for average learners.

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.
