What does 大约 mean?

大约 (dàyuē) is an adverb meaning 'approximately,' 'about,' or 'roughly.'

It comes before a number or quantity to signal an estimate: 大约二十个人 ('about twenty people'), 大约需要三天 ('takes about three days'). It can also mean 'probably' before a whole clause, though this use is a bit less common than with 大概. English speakers should note that 大约 tends to attach to measurable quantities — time, amount, distance, number — where English says 'about' or 'around.'

It is neutral in register and slightly more formal or written than the very colloquial 大概 (dàgài), so you'll see 大约 in news and reports as well as speech. Unlike English 'about,' 大约 is an adverb only and cannot itself be a noun or adjective. Pair it naturally with 左右 (zuǒyòu, 'or so') for a doubly hedged estimate: 大约五点左右 ('around five o'clock or so').

Synonyms

大概dàgài

大概 is more colloquial and also readily means 'probably' and 'the gist.' 大约 is a touch more formal/written and stays closer to the numeric 'approximately' sense.

左右zuǒyòu

左右 means 'or so / around' and follows the number (五点左右, 'around five'). 大约 precedes it. They combine: 大约五点左右.

差不多chàbuduō

差不多 stresses 'almost / about the same' as a target. 大约 gives a neutral numeric estimate without implying nearness to something specific.

Don't confuse 大约 with

大概dàgài

Both mean 'approximately.' 大约 is narrower (mostly numeric estimates, slightly formal); 大概 also means 'probably' and 'the gist' and is more colloquial.
