大约

• Pinyin: dà yuē
• Hanzi breakdown: 大 (big, broadly) + 约 (approximately, agreement)

Meaning

Approximately; about; roughly. Used to give an estimate rather than an exact number.

Commonly placed before numbers or time expressions to indicate approximation. Interchangeable with 大概 in many contexts, though 大约 tends to sound slightly more precise or formal.
