Neden the yok?
is this used when talking about your nationality, like i come from the USA
Yes :) "Ben Amerika'dan geliyorum" but even better would be "Ben Amerikalıyım"
Small correction to your English though...you would have to say "I am from the US." or even better "I am from the US." :)
Ayşegül, "this" var olduğunda hiç bir "the" var olamaz. "from this palace" (bu saraydan) veya "from the palace" (saraydan). :-)
why it's wrong when I use ( I'm) ınstead of ( I am)
