I dpn't understand "que."
I don't understand what "que" is supposed to be in this sentence. Not to be confused with, I already know what qué is.
"Tengo que ir ahora." = I have to go now.
what is "que" in this sentence? I asked my teacher and she said it has no direct translation to english. So I get it, and I don't expect a translation, but why is it there, what does it do, when do I use it, and when do I NOT use it?
