Decir lo que tienes que hacer/ Saying what you have to do

To say that you have to do something in Spanish, you can use tengo que (I have to) followed by the infinitive.

I have to…
Tengo que hacer una llamada.	I have to make a phone call.
Esta noche tengo que quedarme en casa.	I have to stay in tonight.
Tenemos que estar allí a las ocho en punto.	We have to be there at eight o’clock sharp.

To say that you have to do something in Spanish, you can also use debo (I must) and then the infinitive. debo comes from the verb deber.

I must…
esta noche debo irme temprano.	I must leave early tonight.
Debo decirle que no puedo ir.	I must tell her that I can’t come.
No debes llegar tarde.	You mustn’t be late.

To say that you should do something, use debería (I should) and the infinitive.

I should…
Debería llamar a Ana.	I should call Ana.
Debería irme ya.	I should be going now.
Deberías venir a visitarnos.	You should come and visit us.

If you hear someone talking about their pareja (partner), remember that, although it’s a feminine noun, it is used for both men and women.
