Morphology

epochal = epoch (semi-transparent) = epoch + al

The word is built regularly from 'epoch' + '-al', but the modern sense 'extremely significant' is a metaphorical extension from 'marking an epoch' rather than a fully literal composition.

Etymology

The word epochal comes from the word epoch, which comes from Greek epochē meaning 'a fixed point in time'. So an epochal event is one that marks or starts a whole new era and is very important.
