therefore

表示“因此、所以”，用来指出前面所说的原因带来的结果；另有古旧的“为此、为了那件事”用法。

💡 记忆钩子

把 therefore 想成一支从“那件事”指向“前方结果”的箭头：前面先说原因或事实，therefore 把箭头引向“所以接下来会这样”的结论；古旧用法则保留了“为那件事”的原始意味。

先掌握现代英语中表示“因此、所以”的结果用法；古旧的“为此”义项主要在历史文本或仿古语境中遇到。
不要把 therefore 当作普通时间副词来理解，它强调的是前后内容之间的因果或推论关系。

📖 中文释义

adv

core 因此；所以

📖 表示“由前面所说的原因或事实，结果就是这样”，把前文和后面的结果或结论连成一条因果箭头。

💡 常见模式是“原因或事实；therefore，结果”，例如“事实，therefore，结论”。它常用于正式书面语，口语中通常用更随意的“所以”表达同样关系。不要把它只译成“然后”，因为它强调的是因果或推论，而不是单纯的先后顺序。

rare 为此；为了那件事

📖 这是古旧用法，指“为了前面提到的那件事”或“就那件事而言”，保留了“为那件事”的原始意味。

💡 通常出现在古英语、宗教文本或仿古文体中，现代日常英语不这样使用。遇到这种义项时，要根据上下文把它理解为目的或所指对象，而不是现代最常见的“因此”。

🌳 词源

源自中古英语 therfore 等形式，原本相当于“为那件事”；后来重新分析为 there 加 fore，逐渐固定为现代拼写。

From Middle English therfore, therfor, tharfore, thorfore; synchronically a univerbation of there (pronominal adverb) + for, literally “for that (reason)”. The spelling has been changed due to a reanalysis as there + fore (literally “forward from that; thence”). See also therefor, ultimately the same formation. Compare Saterland Frisian deerfoar, Dutch daarvoor, German dafür, Danish and Norwegian derfor, Swedish därför.
