between和in between有咩分別?

between和in between都可用在：指在兩點(時間、空間)的中間
但between是介詞（preposition)，所以要帶出名詞、動名詞等，如：
I sat down between Jo and Diana.（我坐在喬和黛安中間）
There a lot of feeling between them.（他們彼此間芥蒂頗多）
但in between是副詞，不用也不可帶出名詞、或動名詞。
The house was near a park but there was a road in between.（房子在一處公園附近，但兩者之間有一條路）
I see her most weekends but not very often in between.（我週末大多都能見到她，但平時不常見到）
希望幫到你！
