presumptuous

形容人或行为自以为是、擅自作出没有根据的判断，因过度自信而越过了应有的界限。

💡 记忆钩子

把自己想象成未经邀请就跨进别人地盘的人：他先入为主地认定自己有资格，于是擅自决定、评论或干预；这种“越界的自信”就是 presumptuous。

📝 学习建议

学习时先把它和“自信”区分开：presumptuous 通常带有傲慢、冒失和不合适的负面意味，不只是“想当然”。

📖 中文释义

adj

core 自以为是而越界的

📖 指一个人没有充分依据，却因为傲慢或过度自信而擅自作出判断、提出要求或干涉他人，仿佛自己理所当然地有这个资格。核心画面就是“未经允许跨进别人的地盘”。

💡 常见结构是“be presumptuous to do sth”“be presumptuous of sb to do sth”，后面接具体的建议、要求或干涉行为。它通常修饰人、话语或行为，带有正式而强烈的批评意味。不要用它单纯表示“大胆”或“有主见”；如果只是表达自信而没有越界含义，应换用更中性的词。

It would be presumptuous of me to tell you how to run your business.

我如果告诉你该如何经营生意，就未免太自以为是了。

She was presumptuous enough to open my mail without asking.

她竟然自作主张，没问我就拆开了我的邮件。
