Si te equivocas, usa el borrador y vuelve a escribir el título con el rotulador azul.

Because the verb is equivocarse, which is a pronominal verb. In Spanish, you normally say:

• me equivoco = I make a mistake / I’m mistaken
• te equivocas = you make a mistake
• se equivoca = he/she makes a mistake

So the te is part of the verb pattern here, not an extra word you can usually drop.

In this sentence, si te equivocas means if you make a mistake.

Spanish often uses the present indicative after si for real or possible situations in the present or future.

So:

• Si te equivocas, ... = If you make a mistake, ...

This is a very normal pattern:

• Si tienes tiempo, llámame. = If you have time, call me.
• Si llueve, nos quedamos en casa. = If it rains, we’ll stay home.

English sometimes uses present here too, but Spanish learners often expect a future form. Spanish does not use the future after si in this kind of sentence.

So si te equivocarás or si te equivocarás en el futuro would be wrong here.

Usa is the tú imperative of usar. It is giving a direct instruction to one person:

• usa = use

The sentence is telling someone what to do if they make a mistake.

For regular -ar verbs, the affirmative tú command looks like the él/ella/usted present form:

• usar → usa
• hablar → habla
• mirar → mira

So here:

• usa el borrador = use the eraser / use the board eraser

Spanish very often uses volver a + infinitive to mean do something again.

So:

• vuelve a escribir = write again / write it again

This structure is extremely common and natural:

• Vuelve a leer el texto. = Read the text again.
• Vuelve a intentarlo. = Try again.

Spanish does have verbs like reescribir, but volver a escribir is often more natural in everyday instructions, especially in simple classroom language.

Yes. Vuelve is the affirmative tú imperative of volver.

So in this sentence there are two commands:

• usa
• vuelve a escribir

Both are directed at you informally, singular.

If you were speaking to usted, the sentence would change:

• Si se equivoca, use el borrador y vuelva a escribir el título con el rotulador azul.

Good question. Borrador can mean different things depending on context.

Common meanings include:

• draft of a document
• eraser or board eraser

In this sentence, because it says if you make a mistake, use the borrador and write the title again, borrador clearly means something used to erase.

In Spain, this can especially refer to a board eraser. In other contexts, for a small pencil eraser, you might also hear goma or goma de borrar.

So yes, borrador does often mean draft, but not here.

In Spain, rotulador usually means a marker or felt-tip pen.

So:

• el rotulador azul = the blue marker

This is a very Spain-specific everyday word. In many parts of Latin America, people may use different words, such as:

• marcador
• plumón
• sometimes other regional terms

So if you are learning Spanish from Spain, rotulador is the normal word to know.

Con here tells you the instrument used to do the writing:

• con el rotulador azul = with the blue marker

That means the marker itself is blue.

If you said en azul, that would focus more on the colour of the writing:

• escribe el título en azul = write the title in blue

Both can work in some contexts, but they are not exactly the same:

• con el rotulador azul = using the blue marker
• en azul = in blue, in blue colour

The original sentence specifically mentions the tool.

Spanish often uses the definite article where English might not think of using the as strongly.

Here, el título refers to the specific title that the person is supposed to write.

So:

• escribir el título = write the title

This is very natural in Spanish. In classroom instructions, Spanish often uses articles with school objects and specific items:

• Abre el libro. = Open the book.
• Cierra la puerta. = Close the door.
• Escribe el título. = Write the title.

Because Spanish usually leaves out subject pronouns when they are already clear from the verb form.

Here, the commands usa and vuelve already show that the instruction is for tú. Also te equivocas makes it clear that the person is you.

So Spanish normally says:

• Si te equivocas, usa...

not

• Si tú te equivocas, tú usa...

You can add tú for emphasis or contrast, but it is not normally needed.

Because Si te equivocas is an introductory conditional clause, and the main instruction comes after it.

So the structure is:

• Si te equivocas, = If you make a mistake,
• usa el borrador y vuelve a escribir... = use the eraser and write again...

This comma is very standard in Spanish, just as it is often used in English with an opening if clause.

Yes, reescribe el título is grammatically possible and means rewrite the title.

However, vuelve a escribir el título often sounds more everyday and more transparent for simple instructions, especially in a classroom context.

Compare:

• reescribe el título = rewrite the title
• vuelve a escribir el título = write the title again

Both are correct, but volver a + infinitive is a very common pattern in spoken and practical Spanish.

In Spanish, adjectives usually come after the noun.

So:

• el rotulador azul = the blue marker
• el libro rojo = the red book
• la mesa blanca = the white table

That is the normal word order. Putting the adjective before the noun is possible in some cases, but it usually adds a special stylistic or emotional effect and would not sound natural here.

It can mean either, depending on context.

• Te equivocas. can mean You’re wrong.
• Si te equivocas... in this sentence clearly means If you make a mistake...

The wider context decides which meaning is more natural. Since the sentence then talks about erasing and writing again, the meaning here is clearly about making a mistake while writing.

It is informal singular, because it uses tú forms:

• te equivocas
• usa
• vuelve

So it is addressed to one person informally, such as a student, child, classmate, or someone you are on familiar terms with.

A formal version with usted would be:

• Si se equivoca, use el borrador y vuelva a escribir el título con el rotulador azul.
