El giro a la derecha completa la secuencia de pasos.

A la derecha is the normal Spanish pattern for direction: to the right / rightward.

• giro a la derecha = right turn
• girar a la derecha = to turn right

Why not de la derecha?

• de la derecha usually means from the right or the one on the right, depending on context.
• So it would not express the idea of turning in that direction.

Why not just derecha?

• In Spanish, this idea normally needs the preposition a plus the article:
  • a la izquierda
  • a la derecha

This is a very common fixed expression.

Here, giro means turn.

It is a noun, not a verb:

• el giro = the turn
• girar = to turn

In this sentence, el giro a la derecha means the right turn.

Depending on context, giro can also mean:

• a physical turn or rotation
• a turn in a route or set of movements
• even a figurative twist or change

But in your sentence, it is simply the movement or turn to the right.

Both can relate to turning, but they are not always interchangeable.

• giro often focuses on the act or movement of turning.
• vuelta is broader and can mean:
  • a turn
  • a lap
  • a return
  • a spin
  • a trip around something

In an instructional sentence like this one, giro sounds very natural for a directional movement in a sequence.

Examples:

• Haz un giro a la derecha. = Make a right turn.
• Da una vuelta. = Turn around / go for a spin / take a lap, depending on context.

So giro is a good, precise choice here.

Spanish uses definite articles more often than English.

In this sentence:

• El giro = the turn
• a la derecha = literally to the right
• la secuencia = the sequence

Even where English might sometimes leave an article out, Spanish often keeps it.

For example:

• English: Turn right
• Spanish: Gira a la derecha

The article in a la derecha is part of the normal expression.

Completa is the third-person singular present form of completar.

The subject is El giro a la derecha, which is singular, so the verb must also be singular:

• El giro ... completa
• not completan

Basic breakdown:

• completar = to complete
• completa = completes / completes it / does complete, depending on context

So the grammar is:

• subject: El giro a la derecha
• verb: completa
• object: la secuencia de pasos

Spanish word order is often flexible, but this sentence uses the most neutral order:

Subject + verb + object

• El giro a la derecha
  • completa
    • la secuencia de pasos

This is the most straightforward way to say it.

Could Spanish change the order? Yes, sometimes:

• La secuencia de pasos la completa el giro a la derecha.

That version is grammatically possible, but it sounds more marked or emphatic. For a simple explanation or instruction, the original order is more natural.

De pasos means of steps.

So:

• la secuencia = the sequence
• la secuencia de pasos = the sequence of steps

This is a very common Spanish structure:

• un vaso de agua = a glass of water
• una lista de nombres = a list of names
• una secuencia de pasos = a sequence of steps

Spanish often uses de + noun where English uses of + noun or sometimes just a noun used adjectivally.

All Spanish nouns have grammatical gender, even when the thing itself is not male or female.

• giro is masculine: el giro
• secuencia is feminine: la secuencia

This gender affects:

• the article: el / la
• adjectives, if there are any

For example:

• la secuencia completa
• el giro completo

You usually just have to learn the gender with the noun.

A helpful clue:

• nouns ending in -ción are usually feminine:
  la secuencia, la canción, la explicación

Sometimes yes, but the nuance is slightly different.

• a la derecha = to the right / rightward
  This is the standard expression for a right turn.
• hacia la derecha = towards the right
  This can sound a bit less fixed and a bit more directional in a general sense.

For a standard instruction, giro a la derecha is the most natural choice.

Compare:

• Gira a la derecha. = Turn right.
• Se movió hacia la derecha. = He/She moved towards the right.

So in your sentence, a la derecha is the best fit.

It often suggests brings to completion or finishes off the sequence.

So although the basic meaning is completes, the feeling can be:

• this turn is the final element needed
• this turn makes the sequence whole

That is a common use of completar in Spanish:

• completar un formulario = fill out/complete a form
• completar una colección = complete a collection
• completar una secuencia = complete a sequence

So here it is not just belongs to the sequence; it is the element that finishes it.

Yes, it sounds natural, especially in contexts like:

• instructions
• choreography
• movement training
• manuals
• route descriptions
• step-by-step explanations

It has a slightly formal or instructional tone because of words like:

• giro
• secuencia de pasos
• completa

In casual speech, a speaker might simplify it depending on context, but the sentence itself is perfectly natural and correct.

Yes. Spanish could express a similar idea with the verb girar, but the structure would change.

For example:

• Girar a la derecha completa la secuencia de pasos.

That means Turning right completes the sequence of steps.

Difference:

• El giro a la derecha... uses a noun phrase: the right turn
• Girar a la derecha... uses an infinitive phrase: turning right

Both are possible. The original sentence sounds a bit more like it is referring to a specific movement as a named step within the sequence.
