How it's used
Focuses on the scale or extent of a change, typically used with verbs indicating movement or variation like 上升, 下跌, or 增加. It conveys a sense of significant impact or a noticeable shift in data or trends. While it functions as an adverb, it is almost exclusively reserved for formal or professional contexts such as news reports, business presentations, or academic writing.
Examples
Prices have risen substantially this year.
After you lowered the price, did sales increase substantially?
Related words
Common mistake
Avoid using it in casual, everyday conversation when describing small or minor changes, as it implies a dramatic or major shift. It is not interchangeable with 好多, which is a more general quantifier for quantity.
