what is the difference between 完 and 过了 ?
For example, I know these two sentences are correct:
我刚忙完
我刚吃过了
Are they interchangeable? Like this:
我刚忙过了
我刚吃完

Question

Answer

完 means finished.过了 means have done

Answer

To me, both of them mean different things.
我吃过了 means 'I had a meal already / just now' while 我吃完了 means 'I just finished my meal'.
I have never heard people saying '我刚忙过了', it doesn't really make sense, but 我刚忙完了 is very commonly used to express that you're free now after completing the work.
