teach (v.)

古英语 tæcan (过去时 tæhte ,过去分词 tæht )"显示、指出、宣布、演示",也"给予指示、训练、分配、指导;警告;说服",来自于古日耳曼语 *taikijan "显示"(也是古高德语 zihan ,德语 zeihen "指责",哥特语 ga-teihan "宣布"的来源),来自于PIE词根 *deik- "显示、指出"。与古英语 tacen, tacn "标志、标记"有关(见 token )。相关: Taught ; teaching

Lemonade Vendor (Edgar Kennedy), enraged: I'll teach you to kick me!
Chico: you don't have to teach me, I know how. [kicks him]

古英语 tæcan 的通常意义是"显示、宣布、警告、说服"(比较德语 zeigen "显示",来自同一词根);而古英语中"教导、指示、引导"的词更常见 læran ,现代 learnlore 的来源。
