Revisamos la tarjeta de crédito.

Because -amos is the nosotros ending for -ar verbs.

The infinitive is revisar. In the present tense:

• yo reviso
• tú revisas
• él/ella revisa
• nosotros revisamos
• vosotros revisáis
• ellos revisan

So revisamos means we check / we review.

It is also the same form as the preterite for nosotros with -ar verbs, so depending on context it can also mean we checked / we reviewed.

You usually know from the context.

For -ar verbs, the nosotros form in the present and the preterite looks the same:

• Hoy revisamos la tarjeta de crédito. = Today we check / are checking the credit card statement/card
• Ayer revisamos la tarjeta de crédito. = Yesterday we checked the credit card statement/card

Time words such as hoy, ahora, ayer, anoche, esta mañana, etc. usually make the meaning clear.

Spanish often leaves out subject pronouns because the verb ending already tells you who the subject is.

So:

• Revisamos la tarjeta de crédito.
• Nosotros revisamos la tarjeta de crédito.

Both are correct, but the first is more natural in many situations.

You would add nosotros mainly for:

• emphasis
• contrast
• clarity

For example:

• Nosotros revisamos la tarjeta de crédito, pero ellos no.

Because tarjeta is a specific singular feminine noun, so it takes the definite article la.

• la tarjeta = the card
• una tarjeta = a card

In this sentence, la tarjeta de crédito means the credit card or the credit card statement/account, depending on context. It refers to a specific one already known in the conversation.

Because tarjeta is a feminine noun in Spanish.

A good clue is that many nouns ending in -a are feminine, though not all. So:

• la tarjeta
• la mesa
• la casa

The article must agree with the noun:

• feminine singular → la
• masculine singular → el

Because tarjeta de crédito is a fixed noun phrase meaning credit card.

Here, de means something like for / of in a descriptive sense. It is not talking about a specific credit, so you do not use an article.

Compare:

• tarjeta de crédito = credit card
• tarjeta de débito = debit card

You would only use del or de la if you were referring to a specific noun with an article:

• el problema del crédito = the problem of the credit/loan

But in tarjeta de crédito, it is simply the name of the thing.

Yes, revisar is very natural if you mean to check, to look over, or to review something carefully.

Depending on context:

• revisar = check/review/look over
• comprobar = verify/check whether something is correct
• mirar = look at
• ver = see/watch/look at

So:

• Revisamos la tarjeta de crédito. suggests checking it more carefully.
• Miramos la tarjeta de crédito. sounds more like simply looking at it.
• Comprobamos la tarjeta de crédito. suggests verifying details.

In Spain, revisar is a very normal choice.

A simple pronunciation guide:

• Revisamos → reh-bee-SAH-mos
• la → lah
• tarjeta → tar-HEH-ta
• de → deh
• crédito → KREH-dee-toh

A few useful Spain-specific notes:

• j in tarjeta is a strong throaty sound, not an English j
• the stress is:
  • reviSAmos
  • tarJEta
  • CRÉdito

The written accent shows where the stress goes: CRÉ-di-to.

Without the accent, Spanish stress rules would make you expect a different stress pattern. The accent mark helps you pronounce it correctly and distinguishes the standard spelling.

So:

• crédito → stress on the first syllable

If you mean credit cards, it becomes:

• Revisamos las tarjetas de crédito.

Changes:

• la → las
• tarjeta → tarjetas

de crédito stays the same.

Yes. That means We are checking the credit card and emphasizes that the action is in progress right now.

Compare:

• Revisamos la tarjeta de crédito.
  • can mean we check, we are checking, or we checked, depending on context
• Estamos revisando la tarjeta de crédito.
  • clearly means we are checking it right now

In Spanish, the simple present often covers situations where English uses present continuous.

The normal order is:

• Verb + object
• Revisamos la tarjeta de crédito.

This is very standard in Spanish.

You can change the word order for emphasis, but the basic version is the most natural for learners. For example:

• La tarjeta de crédito la revisamos mañana.

That kind of structure is more marked and usually used for emphasis or contrast. The original sentence is the neutral form.

Not always. It can refer to:

• the physical credit card
• the credit card account
• sometimes, depending on context, the credit card statement/charges

So if someone says Revisamos la tarjeta de crédito, the exact meaning depends on the situation:

• checking the card itself
• checking the expenses
• reviewing the account details

Context tells you which one is meant.
