拒绝 is a transitive verb meaning 'to refuse' or 'to reject'—it expresses a firm, deliberate refusal of a request, offer, suggestion, or proposal. The first character 拒 (jù) means 'to resist' or 'to repel', while the second character 绝 (jué) means 'to cut off' or 'to terminate'. Together, they form an emphatic compound suggesting complete and decisive rejection, as if cutting off something at its root. It's commonly used in formal, written, and spoken contexts—from declining an invitation to rejecting a job offer or turning down help.

This word carries a neutral-to-slightly-formal register; it’s more direct and stronger than softer alternatives like 谢谢，不用了 (‘Thank you, no thanks’). It often appears with objects marked by 把 or after subjects performing clear agency: e.g., ‘他拒绝了这个提议’. While it can describe interpersonal refusals, it’s also used in legal, medical, or technical contexts (e.g., immune system rejecting a transplant).
