Conjunciones de subordinación
Subordinating conjunctions join dependent (subordinate) clauses to main clauses. You can recognize a dependent clause by the fact that it cannot stand alone – its meaning is incomplete without the main clause.
Por ejemplo …
Dije que estoy ocupado. – I said that I am busy.
The main clause is I said. What did I say? That I am busy. "I am busy" is incomplete without "I said." I might not in fact be busy, but I said that I was.
Como no tengo dinero, no puedo ir. – Since I don’t have any money, I can’t go.
The main clause is I can’t go. Why can’t I go? Because I don’t have any money. The idea here is not that I don’t want to go, but the fact that I can’t go since I don’t have any money.
Te lo diré cuando nos veamos. – I will tell you when I see you.
The main clause is I will tell you. When will I tell you? When I see you. So "I will tell you" is incomplete without the juxtaposition "when I see you."
