Morphology

irreversibly = irreversible (transparent) = ir + reverse + ible + ly

Forming the adverb by adding -ly to the adjective 'irreversible' is a regular and transparent derivation.

Etymology

Irreversibly comes from the parts ir- meaning 'not' and reverse meaning 'turn back', with -ly making it describe how something happens. So, irreversibly means 'in a way that cannot be turned back' or 'cannot be undone'.
