certainly

副词，表示“确定地、无疑地”，也可单独用作强烈肯定的回答，相当于“当然”。

💡 记忆钩子

把 certainly 想成把事情“钉死”：放在句子里，就是说某事确定无疑；单独回答时，就是把“是”钉得更牢，表示“当然可以”。

📝 学习建议

先掌握“无疑、肯定”这一核心，再记住它单独回答时的“当然”用法。
不要把 certainly 机械地理解成“确实”；它也常表示说话人对判断的高度确信，并不一定是在补充新的事实。

📖 中文释义

adv

common 确定地；肯定地

📖 表示做某事时心里有确定把握，或某个判断是明确成立的；它像把一个动作或判断牢牢钉住。

💡 常用结构是 certainly + 动词，或主语 + certainly + 动词；修饰判断时也可放在句首。这个用法较常见于较正式、较有论证色彩的表达。不要把它误当成表示频率或方式的副词。

She certainly knows how to handle difficult customers.

她肯定知道怎样应对难缠的顾客。
core 无疑；当然如此

📖 用于强调某件事毫无疑问，通常是说话人对事实或判断非常有把握，相当于“无疑”“肯定”。

💡 常见结构是 certainly + be，或主语 + certainly + 动词；在回答或评论中也可放在句首以加强语气。它比普通的肯定语气更强，但不一定表示说话人亲眼证实了事实。中文里不要逢句都译成“确实”，要根据上下文选择“肯定”“无疑”等说法。

This was certainly the right decision.

这无疑是正确的决定。

He certainly made an impression at the interview.

他在面试中肯定给人留下了深刻印象。
core 当然；当然可以

📖 单独回答问题时表示强烈同意或爽快答应，意思接近“当然”“没问题”，是“把肯定钉死”的用法。

💡 常见形式是单独说 certainly，或用 certainly, + 后续说明来接受请求、提议或邀请。语气通常礼貌而明确，正式场合也能使用。它不能在所有“是”或“对”的场合都自然替代普通肯定词，尤其不适合没有请求或选择背景的机械回答。

“Could you send me the address?” “Certainly.”

“你能把地址发给我吗？”“当然可以。”
