decide

决定；作出判断；使某人作出决定。在技术语境中还可指对所有输入都给出正确答案。

💡 记忆钩子

把不同选择像用刀切开一样分开：你切定争议的结果，就是“决定”某事；你把选项切开后选定一个，就是“作出决定”；某种理由把别人推向一边，则是“使某人作出决定”。

📝 学习建议

不要把 decide 只理解成“决定某件事的结果”；它也常表示“自己作出判断或选择”。
学习时先掌握“决定结果”和“自己作出决定”这两个核心义项，再记“促使别人决定”以及计算机领域的专门用法。

📖 中文释义

verb

core 决定结果；解决争议

📖 指经过判断后确定比赛、问题、争议或其他事情的结果，也就是把几种可能性分开并定下一种结果。

💡 常用句型是 decide + 事项，或 decide on + 方案、对象，也可说 decide between A and B。主语可以是人、机构或事件；表示“某事将决定结果”时，主语不一定是作决定的人。

ambitransitive

The committee will decide the winner tomorrow.

委员会明天将决定获胜者。

We need to decide on a date for the meeting.

我们需要确定会议日期。
core 作出判断；决定怎么做

📖 指一个人在考虑之后自己作出判断或选择，重点在“作决定”这个过程，而不是替别人确定结果。

💡 常用句型是 decide to do something，也可说 decide between A and B 或 decide on something。不要在 decide 后直接接动词的进行形式来表示计划；这里通常用不定式表达决定要做的事。

intransitive

After thinking it over, Maya decided to stay.

仔细考虑后，玛雅决定留下来。
common 使某人改变主意

📖 指某种理由、劝告或情况促使另一个人作出决定，常带有把对方推向某个选择的意思。

💡 常见句型是 decide somebody against something，表示使某人决定不选择某事；也可用 decide somebody to do something，但后者较少见且偏正式。不要把这个义项误解为“替某人作决定”，它强调的是影响或促成对方的决定。

transitive

The high cost decided us against buying the car.

高昂的价格使我们决定不买那辆车。
rare 判定所有输入

📖 在计算机理论中，指某个判定程序对一个是非问题的每一种输入都能停下来并给出正确答案；这是“确定结果”在技术领域中的严格用法。

💡 通常用于描述算法、图灵机或问题是否可判定，常见于 decide a problem 或 decide whether... 等技术表达。这里不是日常的“作决定”，而是指程序对所有允许的输入都能完成可靠判定。
rare 切开；分隔

📖 这是古旧用法，直接保留了“把东西切开、分隔”的原始意象，可看作现代“作出区分和决定”之义的词源线索。
