为什么英语中兔子有"rabbit"和"bunny"两个说法？

Usage distinction: rabbit is the general neutral term for the animal; bunny is a cute, affectionate term mostly used for baby rabbits or in children's contexts. 冷知识：bunny本身不是兔子的学名，是对兔子的亲昵可爱称呼，常用来指小兔子。

Example: The little girl petted the soft bunny at the petting zoo. 小女孩在萌宠乐园摸了软乎乎的小兔子。
