Morphology

irrationality = irrational (transparent) = ir + rational + ity

Standard noun formation from the adjective 'irrational' by adding '-ity' to indicate the state or quality of being irrational.

Etymology

The word irrationality starts with ir- ('not') before rational, which comes from the root ratio meaning 'reason' or 'calculation', and you can see the same root in the English word ratio. So, irrationality is the state of being 'not reasonable' or lacking 'reason'.
