ENGLISH QUERTION

意思是我的妻子
mine 是名词性，wife 也是名词，能搭配吗？

我妻子

mine只是"我的"意思

mine后面不加名词

My是形容词性物主代词，修饰wife（名词）, mine是名词性物主代词，当然不能修饰名词了。 就像中文，形容词+名词一样，没有名词+名词
可以说，she is mine.她是我的。

my wife 我的妻子
My and mine 有一定的区别。my 是subject，mine 却是object.
If you say "my wife", "my" is describing "wife". You can't say "mine wife", however you can say, "she is mine", where it means that your wife is belonging to you. Also, the word "mine" can only be used when following a verb (thats why it's an "object".)
