Morphology

irrefragable = ir + refrag + able

Although the negative prefix 'ir-' and suffix '-able' are recognizable, the stem 'refrag' is not a productive or familiar English base, so learners cannot reliably infer the meaning from components.

Etymology

The word irrefragable comes from parts ir- meaning 'not' and refrag- meaning 'to oppose' or 'argue against'. So, something irrefragable is 'not able to be argued against' — it is certain and 'indisputable'.
