Morphology

quadrennial = quadrennium (semi-transparent) = quadrenn + ial

The noun sense is directly related to the four-year period concept and aligns with the form derived from 'quadrennium' plus an adjectival/nominalizing suffix.

Etymology

Quadrennial comes from the parts quadri- meaning 'four' and -ennial meaning 'year', like in annual, so as a noun it means a 'four-year period' or an event that happens every four years.
