THANKS VERY VERY VERY MUCH!
And one more thing to ask(if there isn't a problem)
So When we say This is a house, we say like this:"Hada baitun", or "hada baitu"
And when we say "This is THE house", we say like this "hada albaitu" or "hada baitun".I'm asking this, because in different Student books I met this in wrriten different ways.
Sorry if the questions are little stupid but I obviously have some problems with the understanding of some rules.
