Younger
“Younger” 是 young 的比较级，用于年龄、世代或“显得年轻”的比较。常见搭配：younger brother（弟弟）、younger generation（年轻一代）、look younger（显得更年轻）。

- “Younger voters often care more about climate policy.” (更年轻的选民往往更关注气候政策。)
- “Regular exercise helps him look younger than his age.” (规律运动让他看起来比实际年龄年轻。)
Young 源自古英语 geong，与德语 jung 等同源，属日耳曼语族基础词汇；比较级 younger 用常规 -er 构成。
young + -er：-er 为比较级后缀。最高级为 youngest。
社会讨论中 younger workforce、younger audience 常涉及代际差异与消费习惯；家庭称谓 younger sibling 在英语中不区分弟/妹，需靠上下文。
- 固定搭配: “younger brother/sister” (弟弟/妹妹), “younger generation” (年轻一代), “younger than” (比……年轻)
- 原级: young；最高级: youngest
young（年轻）+ er（更）→ 比别人再年轻一点，就是 younger。
