Morphology

irreversible = reversible (transparent) = ir + reverse + ible

The prefix 'ir-' clearly negates the meaning of 'reversible', making the overall meaning clear.

Etymology

The word irreversible comes from the parts ir- meaning 'not' and reverse meaning 'turn back'. So, it literally means 'not able to be turned back', which is why we use it for things you cannot undo or change.
