Question

为什么on the way home的home前不加to？

Answer 1

因为home在这儿是副词

Answer 2

有道网页http://dict.youdao.com/example/written/on_the_way_to_home/#keyfrom=dict.sentence.details.shumian上的例句:
On the way to home, his friend said: "You are really stupid, why did you mention the whisky?"
回家的路上，他的朋友说：“你真蠢，干嘛提威士忌？
People bursting out flabbergast . On the way to home, his friend said: You are really stupid, why did you mention the whisky?
众人哑然。回家的路上，他的朋友说：你真蠢，干嘛提威士忌？
从这些例句可见，home前是可以加to的。
副词的定义是：起修饰或限制动词或形容词作用、表程度或范围的词，说该句中的home是副词是否正确？
