Morphology

momentous = moment (semi-transparent) = moment + ous

Formally built from 'moment' + '-ous' so the structure is clear, but the sense 'very important' reflects a semantic shift from the common 'short time' sense of 'moment'.

Etymology

Momentous comes from the same root as moment and move and originally meant a 'movement' or something that makes a change. So, something momentous is very important because it can 'move' people or events and change what happens next.
