大大 dàdà greatly
greatly; enormously; (dialect) dad; uncle
汉字
用法
- Adverb made by reduplicating 大, meaning "greatly/significantly," placed directly before a verb.
- Common pattern: 大大提高 (dàdà tígāo) greatly improve, 大大增加 (dàdà zēngjiā) greatly increase.
- Always intensifies a change or action, not a noun's size directly - it's not the same reduplication as describing "a very big house."
- Frequent in news and formal writing to emphasize the scale of a change.
