Morphology

irreversible + process

The meaning 'a process that cannot be undone' is directly derived from combining 'irreversible' (not possible to change back) with 'process' (a sequence of steps or changes). This adjective+noun composition is regular and cross-linguistically common, so a B1 learner who knows both constituents would readily understand the MWE.

Etymology

The noun irreversible process gives a clear picture: irreversible means something you cannot turn back and process is a change, like a broken egg or spilled milk that you 'cannot undo'. So, the phrase means a change that 'cannot be returned to its original state'.
