Questions & Answers about Revisamos la muestra.

Why is revisamos used here?

Revisamos is the we form of the verb revisar.

For regular -ar verbs, the nosotros/nosotras ending in the present is -amos:

• yo reviso = I check/review
• tú revisas = you check/review
• él/ella revisa = he/she checks/reviews
• nosotros/nosotras revisamos = we check/review

So Revisamos la muestra uses the verb form that matches we.

Can revisamos mean both we review/check and we reviewed/checked?

Yes. This is a very common question.

With -ar verbs, the nosotros form of the present and the preterite is often identical:

• present: revisamos = we review / we are reviewing / we do review
• preterite: revisamos = we reviewed / we checked

So the form alone does not always tell you whether it is present or past. Context does that.

For example:

• Ahora revisamos la muestra. = now it is clearly present
• Ayer revisamos la muestra. = yesterday it is clearly past

Why is there no subject pronoun like nosotros?
