‘敲定’ is a compound verb meaning ‘to finalize’ or ‘to confirm decisively’—often used when a plan, agreement, schedule, or decision has been thoroughly discussed and officially settled. The first character 敲 (qiāo) literally means ‘to knock’, evoking the image of knocking on wood or tapping to seal something; the second character 定 (dìng) means ‘to decide’ or ‘to fix’. Together, they convey the sense of ‘locking in’ an outcome with confidence and finality.

This word is commonly used in business, project planning, event organization, and everyday negotiations. It implies that all parties agree and no further changes are expected. While formal enough for professional settings, it’s also widely used in spoken Chinese among friends arranging meetups or students confirming group work details. It carries a tone of resolution and authority—not tentative or provisional, but firm and binding.
