Expert writing Tips
Best practice
Avoid using "vastly large" in formal writing. Opt for single-word adjectives like "vast", "immense", or "enormous" for conciseness and clarity.
Common error
Using both "vastly" and "large" together creates a redundant phrase. "Vastly" already implies great size, so "large" becomes unnecessary. Choose one or the other, or a more precise adjective.

Ludwig's WRAP-UP
In summary, while the phrase "vastly large" aims to emphasize size, it's generally considered grammatically incorrect due to redundancy. Ludwig AI identifies it as such, and although some examples appear in sources like The New York Times and Wikipedia, it is better to use alternatives such as "vast", "enormous", or "extremely large" for clarity and conciseness. The phrase is more likely to appear in neutral contexts like news articles but is less suitable for formal writing.
