Expressing “Roughly” with “dàgài”
大概
How it works
大概 (dàgài) means “roughly,” “approximately,” or “probably,” depending on context. It can be used for:
approximate number or amount
rough time estimate
uncertain judgment or guess
So it has both a quantitative use and a modal use.
Example sentences

Key point
大概 (dàgài) can refer either to approximation in number / time or to uncertainty in judgment. The meaning depends on context.
