Morphology

irregularity = irregular (transparent) = ir + regular + ity

Formed by the adjective 'irregular' plus the noun-forming suffix '-ity', yielding the state or quality 'not regular', which is directly predictable from the base.

Etymology

Irregularity comes from the parts in- 'not' and regular 'steady' or 'following a rule'. So an irregularity is something that is 'not steady' or does not follow a pattern, like an uneven heartbeat or a timetable that keeps changing.
