易错句子We bought fruit at a road side stall.

正确表达We bought fruit at a roadside stall.

roadside 是 road + side 构成的复合形容词，修饰名词时必须连写成一个词，就像 seaside、hillside 一样，中间不能分开。写成 “road side” 会让读者把它当成两个独立的词，不再是一个形容词。

易错句子The hotel is roadside, so it is easy to find.

正确表达It is a roadside hotel, so it is easy to find.

roadside 是只作定语的形容词，只能放在名词前面（a roadside hotel / a roadside stall），不能像普通形容词那样放在 be 动词后面作表语。要说明位置，可以说 by the road，或把 roadside 放回名词前作定语。
