Expert writing Tips
Best practice
Use "millions of millions" when you want to stress an exceptionally large number, especially when a single term like "trillions" might not fully convey the magnitude you intend. However, ensure your audience understands the intended scale, as it can sometimes be perceived as imprecise.
Common error
Avoid excessive use of repetitive quantifiers like "millions of millions" in formal writing. While it can emphasize scale, overuse can make your writing sound less precise or even hyperbolic. Consider using more specific numerical values or established terms like "trillions" for clarity and conciseness.

Ludwig's WRAP-UP
The phrase "millions of millions" serves to emphasize a remarkably large quantity. Ludwig indicates that it is grammatically sound, albeit less precise than alternatives like "trillions". While usable, it's best employed when seeking to impress a sense of immense scale, as opposed to specifying an exact number. Predominantly found in News & Media and academic contexts, it carries a neutral formality. For writers aiming for clarity and precision in formal contexts, substituting with "trillions" or a numerical value is advisable. This term is best suited for descriptive writing where emphasis on scale outweighs the need for exactness.
