?意思：differentwith是一個復合詞，由different和with兩個單詞組成。它的意思是“與…不同”，表示與某人或某物有所區別或差異。

用法：differentwith通常用作形容詞短語，修飾名詞或代詞，表示兩者之間的差異。它也可以作為動詞短語，表示與某人或某物有所不同。

例句：

1. My personality is differentwith my sister's. (我的性格與我姐姐的不同)

2. The new model is differentwith the old one in many ways. (新款式與舊款式在許多方面都不同)

3. I feel differentwith you around. (有你在身邊，我感覺很不一樣)

4. His opinion is differentwith mine, but we respect each other's views. (他的觀點和我的不同，但我們尊重彼此的看法)

5. The culture here is quite differentwith that of my hometown. (這里的文化與我家鄉的很不一樣)

同義詞及用法：與differentwith意思相近的詞語有：differ from、vary from、be distinct from等。它們都可以表示兩者之間存在差異或區別。：

1. My personality differs from my sister's.

2. The new model varies from the old one in many ways.

3. I feel distinct from you around.

4. His opinion is not the same as mine, but we respect each other's views.

5. The culture here is quite unlike that of my hometown.

需要注意的是，differentwith和這些同義詞的區別在于它強調的是兩者之間的差異性，而不是簡單的不同或相異。因此，在使用時需要根據具體語境選擇合適的詞語。

這個differentwith，乃是一復合詞也。非但能做形容詞短語，亦可作動詞短語。與differ from、vary from、be distinct from等同義之辭意近，然強調兩者之間的差異。用之當慎重，須根據上下文擇其宜也。
