Morphology

irreversibility = irreversible (transparent) = ir + reverse + ible + ity

Formed by adding the nominalizing suffix '-ity' to the adjective 'irreversible' to denote the state or quality of being irreversible.

Etymology

Irreversibility breaks into ir- meaning 'not', reverse meaning 'to turn back', and -ability meaning 'can'. So irreversibility is the idea that something 'cannot be turned back', which is why we use it for actions or processes that cannot be undone.
