Deber estar vs deber ser
 

Do they have the same meaning?

No.



1. El debe estar frío= He must be cold

1. El debe ser frío = He must be cold

;)

The difference between the two is really the same as the difference between verbs ser and estar. Here are a few threads discussing those differences.

The word are relatively the same although they haven't the same meaning in the Spanish.

El debe ser honesto

Debe ser honesto

You can't use Debe estar honesto.

He most honest.
In the particular of the phrase you can see that they have almost the same, but you can use them in different situations.

Bebe ser honesto.

Debe estar en lo correcto.

As you can see the phrases are totally distinct.

Sincerely yours.

How's this?

The dog must be friendly, he always wags his tail at everyone.
El perro debe ser simpático, siempre se menea el rabo a todo el mundo

She must be a natural blonde.
Ella debe ser una rubia natural.

The restaurant should be nearby, I can smell the food.
El restaurante debería estar cerca de aquí, puedo oler la comida.

The cream must be whipped for 10 minutes.
La crema debe estar batido por diez minutos.

Can estar be used for a temporary state?
Puede estar estar usado en un estado transitorio?

He must be honest for an hour.
El debe estar honesto por una hora.

When you guess, the right construction is "debe de".

El agua de la alberca debe de estar muy fría. Nadie está nadando.
Water in the pool must be too cold. Nobody is swimming.

Debes de estar cansado después de un viaje tan largo.
You must be tired after such a long trip.


When you state the way things must be (for reasons of moral or duty, for example), "deber" isn't followed by the preposition.

No debes golpear a tu hermano.
You must not hit your brother.

Deberíamos ayudar a la gente pobre.
We should help poor people.

Debe tomar las medicinas cada seis horas.
He must take his pills every six hours.


Being honest is a character feature, which are never to be expressed with "estar".

la crema debe ser batido. Why ser? Is this an example of Definitive Characteristics Even if not Permanent.?

Batida.

I hope someone else will have a more technical answer on this, but "la crema debe estar batida durante 10 minutos" it would mean that after those 10 minutes the cream will go back to it's non-whipped state. :thinking:

The 'debe ser batida' structure is the passive voice. The passive voice isn't used in Spanish nearly as much as it is used in English. Spanish has another way to say it passively (using the impersonal 'se').

The passive voice in Spanish always uses the verb 'ser', plus a past participle that acts as an adjective (technically called a subjective complement). The verb 'ser' is technically called a 'copula'.

Thanks, guys. Don't know how you remember all this stuff.
