Maybe,there is something,I really don't understand.. 是什么意思?

可能有些事我真的不懂

“Maybe,there is something,I really don't understand.. ”
连在一起就不是上面这个意思了

there is something I really don't understand
可能有些我真的不知道的事情。
there is something，I really don't understand
可能有些事情，但我真的不知道。

是的,跟楼上说的一样,连起来跟不连起来是不一样的意思的.

maybe there is something (that/what)i really dont understand.
这里就有一个从句了,只是把that/what省了,意思是可能有一些事情我是不明白的.

maybe,there is something,i really dont understand.
也许吧,也许是有点问题/有些事情/有点东西,但我真的不清楚/不明白/不了解/不确定.
这个的具体意思,要看上下文,看语境.

Maybe,there is something,I really don't understand..

对于一些事情,或许我还不够成熟.

也许，有的事情我真的不明白。

或许有些事情，我真的不明白
