repudiate 是及物动词，后接宾语，不能用介词 against。中文“反对”容易让人误加 against，但 repudiate 本身就表示“拒绝承认/履行”，应直接说 repudiate something。
Not this
The government repudiated to pay the debt.
Use this
The government repudiated the debt.
repudiate 不能接不定式 to do，只能接名词或名词短语作宾语。这是把 refuse to do 的用法错误套用到 repudiate 上；repudiate 的宾语是债务本身，而非“支付”这个动作。
Not this
Repudiate the deal caused conflict.
Use this
Repudiating the deal caused conflict.
动词原形不能作主语。要表达“拒绝这个协议”这件事作主语，必须用动名词形式 repudiating，即 repudiating the deal。

语域：formal 常见场景：legal documents and contracts、formal political statements、academic writing、financial and debt contexts repudiate 是偏正式（书面）的动词，多用于法律、政治、学术或金融等正式场合，表示正式拒绝承认、拒绝履行或驳斥。日常口语中较少见，更常用 refuse、deny 或 reject。
这些词都以 -iate 结尾，但读音并不相同。没有词与 repudiate /rɪˈpjuːdieɪt/ 完全押韵；radiate /ˈreɪdieɪt/ 的结尾 /di.eɪt/ 与 repudiate 相同，但重音位置不同。appreciate、initiate、negotiate、associate 中的 -iate 常读作 /ʃi.eɪt/，与 repudiate 的 /di.eɪt/ 不同。
