sure
释义
Confident that something is true or will happen; having no doubt.
确信的;有把握的

可靠的;必定的
Certainly; yes (informal).
当然;的确(非正式)
词根拆分
词根派生sure 经古法语直接来自拉丁 sēcūrus(「无忧的、安全的」)。含义从「安全」滑向「确定」:一样东西既安全又可靠,你就能对它确信。所以 a sure thing 是可靠到让你不再担心的事,make sure 就是「消除一切疑虑」。
词根 sur 还连着 9 个词使用指南
- be sure of/about(状态):I'm sure of the date——对某事实有把握
- be sure to do(叮嘱):Be sure to call me——提醒,近乎命令
- make sure (that)(行动):Make sure the gas is off——采取措施消除疑虑
- for sure(非正式):I'll be there for sure——一定
- sure 作副词偏口语、偏美式:'Sure, I'll come' 或 'It sure is hot'——正式书面语优先用 certainly 或 surely。

易混词辨析
sure 与 certain:都表示「没有疑虑」,但 sure 更个人、更口语(I'm sure he'll come),certain 更坚定、更客观(It is certain to rain / a certain outcome)。陈述事实和正式语境用 certain,日常表自信用 sure。
