Where does the said "tan" at the end of this last word come from?
Is it supposed to be read out loud like that, and does it only exist after "female endings"?
I meant at the end of a sentence, but my grammar knowledge is still pretty basic after years of school.
This is a seemingly simple question, but it has a very confusing answer. It's nunation and it's used in high Arabic (classical Arabic, in poems, in the Qur'an etc). When speaking, you would not use this ending. I would suggest reading up on it a bit just to understand, but don't worry too much about it yet at this level in Arabic. Good question!
