Questions & Answers about Revisó el medicamento.

What tense is revisó?

Revisó is the pretérito indefinido (the simple past / preterite) of revisar.

It is the 3rd person singular form, so it can mean:

• he checked/reviewed
• she checked/reviewed
• you (formal, singular) checked/reviewed

So the sentence gives a completed past action.

Why does revisó have an accent mark?

The accent mark shows the stress and also helps distinguish it from other forms.

• reviso = I check / I am checking
• revisó = he/she/you formal checked

So the accent is important both for pronunciation and meaning.

Who is the subject in this sentence?

The subject is not stated explicitly. Spanish often leaves subject pronouns out because the verb ending already gives that information.

With revisó, the subject could be:

• él = he
• ella = she
• usted = you (formal)

So without more context, you cannot know exactly which one it is.
