No entiendo el uso del "that" en esta oración, Don’t forget, we have that doctor’s appointment tomorrow.

Question

No entiendo el uso del "that" en esta oración.

Hi Peter, listen, don’t forget, we have that doctor’s appointment tomorrow.

Answer 1

I don't quite agree with Lorenzo, because I think it's very common to hear "don't forget we have that doctor's appointment tomorrow".

That one (referring to the appointment) that we made last week. Or: That one that we were talking about.

I never really thought about it, but I think it implies that both parties have prior knowledge...

Don't forget to read that book! ---means we've discussed this before and you know which book I'm referring to.

Gracias, debe ser por eso que Lorenzo no tiene ningun voto. - tomasxenix, Sep 9, 2011

You hit the nail on the head, MLucie! - gintar77, Sep 9, 2011

Answer 2

Se refiere a la cita, no al médico. ("esa cita", no "ese médico").

En esta frase, "doctor's" funciona como un adjetivo modificando a "appointment".

Answer 3

It's short for "Don't forget we have that doctor's appointment which/that I mentioned earlier tomorrow."

Yes! - MLucie, Sep 9, 2011

Answer 4

The sentence is correct and so is gintar's explanation, but in American English it would be more common to say:

Hi Peter. Listen, don’t forget that you have a doctor appointment tomorrow.
