Reviso el medidor antes de pagar el monto.

Reviso is the first-person singular present tense of revisar.

So it means I check, I inspect, or I look over, depending on context.

• yo reviso = I check
• tú revisas = you check
• él/ella revisa = he/she checks

In this sentence, reviso el medidor means I check the meter.

Spanish often drops subject pronouns when the verb form already shows who is doing the action.

Since reviso clearly means I check, the yo is optional.

• Reviso el medidor... = natural and common
• Yo reviso el medidor... = also correct, but adds emphasis or contrast

You might include yo if you want to stress that I, not someone else, do it.

Spanish uses articles like el, la, los, and las more often than English does.

So where English might say I check the meter or sometimes just I check meter readings in a broader context, Spanish usually wants the article:

• el medidor = the meter

Leaving out el here would sound incomplete or unnatural in normal Spanish.

The same thing happens with el monto.

Medidor usually means meter or measuring device.

In everyday Latin American Spanish, it often refers to a utility meter, such as:

• an electricity meter
• a water meter
• a gas meter

The exact meaning depends on context. By itself, medidor is a general word for something that measures.

After antes de, Spanish uses an infinitive when the subject stays general or is understood.

So:

• antes de pagar = before paying
• literally: before to pay

This is a very common structure in Spanish:

• antes de salir = before leaving
• antes de comer = before eating
• antes de firmar = before signing

So antes de pagar el monto means before paying the amount.

Because antes de is followed by an infinitive when you are talking about an action in a general way, not a fully conjugated clause.

Here, pagar works like paying in English:

• antes de pagar = before paying

If Spanish uses a full clause with a different subject, it often switches to antes de que + a conjugated verb:

• antes de que él pague = before he pays

But in your sentence, that is not necessary. The simpler infinitive structure is the natural choice.

Monto means amount, especially a money amount.

So pagar el monto means pay the amount.

In Latin America, monto is widely understood and is common in formal, business, billing, banking, or administrative contexts. In everyday speech, people might also say:

• pagar la cantidad
• pagar el total
• pagar la cuenta depending on context

So monto is correct, but it can sound a bit more formal or transactional than some other options.

It is correct, but how natural it sounds depends on context.

• In a bill, invoice, bank, or official payment context, pagar el monto sounds fine.
• In casual speech, native speakers might more often say:
  • pagar la cuenta = pay the bill
  • pagar el total = pay the total
  • simply pagar if the object is obvious

So the sentence is grammatical and natural, especially in a formal or utility-payment setting.

Yes. Depending on the country and the nuance, you might hear other verbs such as:

• verificar = verify
• checar or chequear = check
• controlar = check/monitor in some contexts

For example:

• Verifico el medidor antes de pagar el monto.
• Checo el medidor antes de pagar el monto. in some regions

Still, revisar is a very solid, widely understood choice in Latin American Spanish.

Spanish, like English, often uses the present tense for routines, habits, or general actions.

So Reviso el medidor antes de pagar el monto can mean something like:

• I check the meter before paying the amount
• I usually check the meter before paying

It does not have to mean only what is happening right now. The present tense often expresses a normal procedure or habit.

Yes, but the original order is the most neutral and straightforward.

Original:

• Reviso el medidor antes de pagar el monto.

You could also say:

• Antes de pagar el monto, reviso el medidor.

That version puts more focus on the timing: Before paying the amount, I check the meter.

Both are correct. The first sounds slightly more neutral, and the second slightly more emphatic about before paying.

No. None of the words in Reviso el medidor antes de pagar el monto need a written accent mark.

Words:

• reviso
• el
• medidor
• antes
• de
• pagar
• el
• monto

Even without written accents, each word still has a natural spoken stress pattern, but orthographically, no accent marks are needed here.
