“爱好”的英文是 "hobby"。

"Hobby" 来自于中世纪拉丁语 "hobbitus"，意思是 "喜欢玩耍的人"。后来英语中 "hobby" 的意思变成了指一个人喜欢做的非正式或非职业性的活动。

例句：

My hobby is reading. (我的爱好是阅读。)
She has many hobbies, including knitting and gardening. (她有很多爱好，包括编织和园艺。)
He spends all his free time playing video games, which is his favorite hobby. (他把所有空闲时间都用来玩电子游戏，这是他最喜欢的爱好。)
