词根学习:tend / tens / tent

关键点:核心义是“强/支撑/加固”。把 fortis 想成一股“承重力”:能把结构顶住(fort/fortress),也能把力量推出去(effort),还能把人心扶稳(comfort)。拉丁 tendere = stretch(伸、拉、趋向)。把它想成“力场/要塞”:一方面是 strong,一方面是把东西“加固/支撑起来”。tend- 为动词词干,tens- / tent- 为过去分词词干变体,表“被拉伸、紧张、意图”。(Etymonline: https://www.etymonline.com/word/extend)

目录

A. 意象化理解

  • 伸/拉 从“物理拉伸”到“延伸、倾向、意图、紧张”。extend = 伸出去 → 延伸;intend = 伸向(目标)→ 打算;attention = 伸向(某点)→ 注意。

  • tension = 被拉紧(的状态)→ 紧张;contend = 一起拉(争)→ 竞争、主张。

  • (技术语境):把系统当作“城防工程”:fortify=加固边界;effort=把力打出去;comfort=给用户“稳住”的支撑。

  • 三条路径:fort/fortress(防御)→ effort(出力)→ comfort/fortitude(扶稳/坚韧)。
