Revisamos el registro.

Because revisamos is the first-person plural form of revisar, so it means we review / we check or we reviewed / we checked, depending on context.

The ending -amos tells you the subject is we.

Yes. With -ar verbs, the nosotros form in the present tense and the preterite can look exactly the same.

So revisamos can mean either:

• we review / we are reviewing
• we reviewed

You usually tell which one it is from context, time expressions, or the wider conversation.

For example:

• Hoy revisamos el registro. = Today we review / are reviewing the record.
• Ayer revisamos el registro. = Yesterday we reviewed the record.

Spanish often leaves out subject pronouns because the verb ending already shows who is doing the action.

So:

• Revisamos el registro.
• Nosotros revisamos el registro.

Both are correct, but the version without nosotros is more natural in many situations.

You might include nosotros for emphasis, contrast, or clarity:

• Nosotros revisamos el registro, pero ellos revisan los informes.

Revisar usually means to check, to inspect, to look over, or to review.

In this sentence, it suggests that we are examining something carefully rather than just casually looking at it.

Depending on context, revisar could mean:

• checking for errors
• inspecting something
• going through a document or system
• reviewing information

So it is broader than just to look at.

Registro is a masculine noun, and its exact meaning depends on context. It can mean things like:

• record
• register
• log
• entry
• registry

So el registro could be:

• a written record
• a computer log
• an official register
• a file or entry in a system

It can also mean register in the sense of style or level of language, but that is a different context.

Spanish often uses an article where English might not.

Here, el registro means the record / the register / the log — a specific one that the speaker and listener already know about.

Compare:

• Revisamos el registro. = We review the record.
• Revisamos un registro. = We review a record.

So el makes it definite and specific.

Yes, registro is masculine, which is why it uses el.

A common clue is the ending -o, since many nouns ending in -o are masculine:

• el libro
• el documento
• el registro

This is not a perfect rule, but it works often.

Yes. This is a very normal Spanish sentence structure.

The basic pattern is:

• verb + object

because the subject is omitted.

If you include the subject, it becomes:

• Nosotros revisamos el registro.

That is also normal.

Spanish word order is fairly flexible, but Revisamos el registro is the most straightforward and natural order here.

A simple English-friendly approximation is:

reh-bee-SAH-mos el reh-HEES-tro

A few useful pronunciation points for Spain:

• v in revisamos is pronounced like a soft Spanish b/v sound, not a strong English v
• g before i in registro sounds like the Spanish j sound, a throaty sound
• the r in registro is a light tap, not a strong English r

A more accurate IPA pronunciation would be roughly:

[reβiˈsamos el reˈxistɾo]

Yes. That would mean we are reviewing/checking the record and puts more emphasis on the action being in progress right now.

Compare:

• Revisamos el registro. = We review / we are reviewing / we reviewed, depending on context
• Estamos revisando el registro. = We are reviewing the record right now

Spanish often uses the simple present where English might prefer the present continuous, so Revisamos el registro can still sound natural in situations where English would say We are reviewing the record.

You would change the verb form.

For example:

• Reviso el registro. = I review/check the record
• Revisas el registro. = You review/check the record
• Revisa el registro. = He/She/You formal reviews/checks the record

So the part that changes is mainly the verb ending. The object el registro stays the same unless the thing being reviewed changes.
