Grammar Patterns

cumulative + noun (effect / damage / impact / improvement / knowledge / rise)

Usage Note

Common Mistakes

Common collocations
  • cumulative total
  • cumulative score
  • cumulative sum
  • cumulative number
  • cumulative cost

  • cumulative distance
Synonyms
  • total

Common Mistakes

The cumulative price of this single book is $20.

'cumulative' describes a combined total, not a one-off price.

Sense: adjective/1

'Cumulative' describes a steady build-up of similar parts over time, with a neutral or factual tone. 'Accumulating' is more dynamic and verb-like ('accumulating evidence') but often interchangeable. 'Mounting' adds emotional weight — mounting debts or mounting pressure suggest a problem that feels urgent and hard to stop. 'Growing' is the broadest term and can apply to anything that increases in size, number, or intensity ('growing interest', 'growing concern'), without the specific sense of layer-by-layer addition. 'Snowballing' implies accelerating speed — a snowballing problem gets worse faster and faster, whereas a cumulative effect may build at a steady pace. For neutral, measured descriptions of gradual build-up — like the effect of study over a semester — 'cumulative' is the most precise and formal choice.

Etymology

LatinFrenchEnglish

From Latin 'cumulatus', meaning 'heaped up', the past participle of 'cumulare' ('to heap up'), which comes from 'cumulus' ('a heap'). The word travelled into English through French 'cumulatif' in the early 1600s, keeping the image of one thing piled on top of another — much like sand heaping up grain by grain.
