anger (v.)

13世纪, “刺激, 恼怒, 挑衅”, 来自古北欧语 angra “悲伤, 烦恼, 苦恼; 恼怒, 冒犯”, 来自古日耳曼语 *angaz (也是古英语 enge “狭窄, 痛苦”, 中荷兰语 enghe, 哥特语 aggwus “狭窄” 的来源), 来自PIE *anghos, 后缀形式为根 *angh- “紧绷, 痛苦地收缩, 痛苦”.

在中古英语中, 也指身体上的痛苦. 意思是“激怒, 使之愤怒”, 来自14世纪末相关: Angered; angering.

anger (n.)

13世纪中叶, “敌对态度, 恶意, 糜烂” (也有“苦恼, 痛苦; 苦恼, 痛苦” 之意, 现已过时), 来自古北欧语 angr “苦恼, 悲伤, 忧愁, 苦难”, 来自原日耳曼语 *angaz (来自PIE根 *angh- “紧绷, 痛苦地收缩, 痛苦” ). 与德语 Angst 同源. “愤怒, 忿怒” 的意义是14世纪初的.

From the sense of oppression, or injury, the expression was transferred to the feelings of resentment naturally aroused in the mind of the person aggrieved. In the same way, the word harm signifies injury, damage in English, and resentment, anger, vexation in Swedish.
The idea of injury is very often expressed by the image of pressure, as in the word oppress, or the Fr. grever, to bear heavy on one. [Hensleigh Wedgwood, “A Dictionary of English Etymology,” 1859 ]

古北欧人也有 angr-gapi “轻率, 愚蠢的人”; angr-lauss “无忧无虑”; angr-lyndi “悲伤, 低落的情绪”.
