At times, the word "have" means "possess". We also use "have" to express the idea of obligation. We say that someone "has to do" something. In Spanish, when we use "have" to express obligation, we use the "R" form of the other verb but we also insert the word "que". The word "que" normally means "that", but in this case, it is just used to indicate that "have" means "have to do" not "have something".

We know that we can use "have" for possession, but also for "obligation". We can say that someone "has" something, but also we can say that someone "has to do" something. In this case we have to insert the word "que" and follow it with the "R" form of the verb that tells us what someone has to do.

If we use a pronoun direct object, we will have to put it in front of the entire verb phrase. In Spanish you can never split a verb phrase.
