Hello every one,
I will start flooding this thread with questions from now on.
I know we would say ˋⲛⲑⲟϥ ⲛⲁⲓ... to express the English of "he would ...".
So how can we say the following:
1- he should have done ...
2- he could have done ...
3- he must have done ...
4- he used to have ... (he had ...)

No, there is nothing corresponds exactly to the English "would"
"would" will be translated differently depending on the context
but in all cases "ⲛⲑⲟϥ ⲛⲁⲓ" is not correct at all
tell me in which context u want to use "would" and i'll tell u its translation

So how can we say the following:
1- he should have done ...
2- he could have done ...
3- he must have done ...
4- he used to have ... (he had ...)

1. ⲛⲁϥ ˋⲥϣⲉ ˋⲛⲧⲉϥˋⲓⲣⲓ ˋⲙ(ˋⲛ)......
2. ⲛⲁϥ ˋϣˋⲓⲣⲓ ˋⲙ(ˋⲛ)....
3. ⲛⲁϥ ϩⲱϯ ⲉⲣⲟϥ ˋⲛⲧⲉϥ.....
4. ⲛⲉ ⲟⲩⲟⲛ ˋⲛⲧⲁϥ ˋⲙ(ˋⲛ).... [ he had]
