dissuade
释义
To talk someone out of doing something; to advise someone against an action
劝阻，劝某人不要做某事
词根拆分
词根派生dis-（分开、反向）+ suade（来自 suādēre「劝告」）。persuade 的镜像：不是把某人说甜、推向某个行动，而是劝他*远离*那件事。这种反转体现在语法上——dissuade sb FROM doing sth，而不是「to do」。
词根 suad 还连着 4 个词使用指南
- dissuade sb from doing sth（标准搭配）：dissuade her from leaving，注意是 FROM + -ing，与 persuade 的「to do」相反。
- dissuade sb from sth：dissuade him from the plan。
- 常见错误：「dissuade sb to do」是错的——dis- 的反向只配 from，不配 to。
- 语域：偏正式；口语里人们常说「talk someone out of」。

易混词辨析
dissuade vs deter — 两者都让人停手，但 dissuade 靠劝说与讲理（把人说服别做），deter 靠恐惧或障碍（罚则、风险、阻碍让人却步）。朋友 dissuade 你；高额罚款 deter 你。
