Si cometo un fallo, prefiero corregirlo enseguida y seguir trabajando.

After si for a real or possible condition in the present or future, Spanish normally uses the present indicative, not a future or conditional form.

So:

• Si cometo un fallo... = If I make a mistake...

This is the normal pattern for real conditions:

• Si tengo tiempo, voy. = If I have time, I go / I’ll go.
• Si llueve, nos quedamos en casa. = If it rains, we stay home.

Using si cometeré or si cometería would be incorrect here.

Cometo comes from the infinitive cometer, which means to make / to commit in expressions like make a mistake.

It is the 1st person singular present indicative:

• yo cometo = I make / I commit

Full present tense of cometer:

• yo cometo
• tú cometes
• él/ella/usted comete
• nosotros/nosotras cometemos
• vosotros/vosotras cometéis
• ellos/ellas/ustedes cometen

In Spanish, cometer is very commonly used with things like:

• cometer un error
• cometer un fallo
• cometer un delito

Both can mean a mistake or an error, but they are not always identical in tone or use.

• un error = a more general, standard word for mistake/error
• un fallo = can also mean mistake, but it can additionally mean fault, failure, or defect, depending on context

In Spain, fallo is very common in everyday speech. In this sentence, cometer un fallo sounds natural and conversational.

Compare:

• He cometido un error. = I’ve made an error/mistake.
• He cometido un fallo. = I’ve made a mistake.

In many contexts here, they are very close in meaning.

Because preferir is a stem-changing verb. In the present tense, the e in the stem changes to ie in most forms.

So:

• preferir → prefiero

Present tense:

• yo prefiero
• tú prefieres
• él/ella/usted prefiere
• nosotros/nosotras preferimos
• vosotros/vosotras preferís
• ellos/ellas/ustedes prefieren

Notice that nosotros and vosotros do not have the stem change.

-lo is a direct object pronoun meaning it.

• corregir = to correct
• corregirlo = to correct it

Here, lo refers back to un fallo.

So the structure is:

• prefiero corregirlo = I prefer to correct it

Spanish often attaches object pronouns to an infinitive:

• hacerlo = to do it
• verlo = to see it
• arreglarlo = to fix it

No, that would not be natural here.

With preferir + infinitive, if you want to use an object pronoun for the infinitive, the normal place is attached to the infinitive:

• Prefiero corregirlo. = I prefer to correct it.

You might also see pronouns before a conjugated verb in other structures, but with this sentence, corregirlo is the straightforward and correct form.

So use:

• prefiero corregirlo not
• lo prefiero corregir

Enseguida means something like:

• right away
• straight away
• immediately
• at once

In Spain, it is a very common everyday word.

So:

• corregirlo enseguida = to correct it right away

A similar word is inmediatamente, but enseguida often sounds a bit more natural and conversational.

Because seguir + gerund is a common structure meaning to keep doing something or to continue doing something.

• seguir trabajando = to keep working / to continue working

Here:

• seguir = to continue
• trabajando = working

So the phrase means the speaker wants to correct the mistake and then continue the activity already in progress.

Other examples:

• Sigo estudiando. = I keep studying.
• Después de comer, siguió leyendo. = After eating, he/she continued reading.

Because after seguir, Spanish often uses a gerund to express continuing an ongoing action.

• seguir trabajando = to continue working

The gerund is formed like this:

• -ar verbs → -ando
• -er / -ir verbs → -iendo

So:

• trabajar → trabajando

If you said seguir trabajar, that would be incorrect.

Because one prefiero can govern both infinitive phrases:

• corregirlo
• seguir trabajando

So the structure is:

• prefiero [corregirlo] y [seguir trabajando]

This is like English:

• I prefer to correct it and keep working.

You do not need to repeat prefiero unless you want extra emphasis.

Y means and. It links two actions that the speaker prefers to do:

1. corregirlo enseguida
2. seguir trabajando

So the idea is:

• first, correct the mistake right away
• then, continue working

It is coordinating two infinitive phrases after prefiero.

The comma separates the introductory if-clause from the main clause.

• Si cometo un fallo, = If I make a mistake,
• prefiero corregirlo enseguida y seguir trabajando. = I prefer to correct it right away and keep working.

This is also very natural in English:

• If I make a mistake, I prefer...

In short sentences, punctuation can vary a little in informal writing, but the comma here is standard and helpful.

It would be understood everywhere, but some parts feel especially natural in Spain.

In particular:

• fallo meaning mistake is very common in Spain
• enseguida is common across the Spanish-speaking world, including Spain

In many Latin American varieties, people might be a bit more likely to say:

• Si cometo un error, prefiero corregirlo de inmediato y seguir trabajando.

But your original sentence is perfectly clear and natural, especially in Spain.

Yes, depending on context, it can suggest either:

• if I make a mistake or
• when(ever) I make a mistake

Here it expresses a general personal habit or preference, so in English the idea is close to:

• If I make a mistake, I prefer to correct it straight away and keep working.
• Whenever I make a mistake, I prefer to correct it straight away and keep working.

Spanish often uses the same structure for this kind of general condition.

Yes. The most natural place here is after corregirlo, but Spanish allows some flexibility.

Current version:

• prefiero corregirlo enseguida y seguir trabajando

Possible alternative:

• prefiero enseguida corregirlo y seguir trabajando

This is grammatically possible, but less natural in everyday speech. The original word order sounds smoother and more idiomatic.

So for a learner, the best choice is:

• corregirlo enseguida
