Spanish tip -

Do you know the difference between "deber" and "deber de"? This article explains both uses and gives you some examples, so you can understand it.

The first diference, at a glance, is that one of these forms includes the preposition "de" ("of" ). But the main difference is in meaning:

In both cases (Deber / Deber de), we will conjugate the verb "deber", according to the tense, mood and person we may need. Some examples:

Debo ir a la escuela. (I must go to school.) - Present tense, indicative, first person singular (Yo debo)Ana debería de llegar en una hora. (Ana should be arriving in one hour.) - Conditional simple, indicative, third person singular.
Note this difference is not always known by native Spanish speakers! It is quite common to hear someone (native Spanish speaker) saying: "Debe ser tarde", when in fact, what he/she means is : "It must be late", that is, expressing the idea of doubt or uncertainty.

So, that person should be saying "Debe de ser tarde", because "Debe ser tarde" implies obligation and "Debe de ser tarde" implies doubt, uncertainty.

In short:

- Deber + infinitive → Obligation
- Deber de + infinitive → Doubt, uncertainty

I have created a quiz ao you can practice and learn to differentiate and use "deber" and "deber de".
