Sense: noun/1

All four words describe the quality of being important, but momentousness carries a stronger implication of future-shaping impact. 'Significance' is the broadest and most neutral term — a small finding can have statistical significance, whereas momentousness always refers to a major event. 'Gravity' emphasises seriousness and often carries a negative or solemn tone, as in 'the gravity of the accident,' while momentousness can describe positive turning points. 'Weight' is less formal and suggests a burden of importance: 'the weight of the decision rested on her shoulders.' 'Consequence' highlights the outcome dimension: the importance lies in what will follow. Use momentousness when you want to stress that an event will alter the future, not just that it matters now.

Etymology

LatinFrenchEnglish

Momentousness is built from 'momentous' (meaning of great importance) and the noun-forming suffix '-ness.' 'Momentous' itself comes from 'moment,' which in Latin (momentum) carried the sense of 'weight' or 'moving force' before it came to mean a brief period of time. By the 17th century, English speakers had extended 'moment' to mean 'importance' in phrases like 'a matter of great moment,' and the adjective 'momentous' was coined to describe events that carry such weight. The noun 'momentousness' followed, giving a name to the quality itself.
