Questions & Answers about Debemos razonar.

What does debemos mean here?

Debemos is the 1st person plural form of deber in the present tense.

So it means we must, we should, or we ought to, depending on context.

In Debemos razonar, it usually means something like:

• We must reason
• We should think this through
• We need to be rational

Spanish deber + infinitive often expresses obligation, duty, or strong advice.

Why isn’t nosotros included?

Spanish often drops subject pronouns because the verb ending already shows who the subject is.

• debemos = we must / we should

So (nosotros) debemos razonar and debemos razonar mean the same thing.

Including nosotros is possible, but it usually adds emphasis, contrast, or clarity:

• Nosotros debemos razonar, no ellos.
  We should reason, not them.

What form is razonar?

Razonar is an infinitive, the basic dictionary form of the verb, like to reason in English.

It ends in -ar, so it is a regular -ar verb.

Here, after debemos, the infinitive is used because Spanish commonly builds this structure as:

• deber + infinitive

So:

• debemos razonar = we must reason
