Pasa la silla un poco a la derecha, por favor.

That is a very common question.

In this sentence, pasar has the sense of to move/shift something along. In Spain, you can use pasar for moving an object from one position to another, especially in everyday speech.

So Pasa la silla... means something like:

• Move the chair...
• Shift the chair...

It does not mean pass the chair in the English sense of handing it over, unless the context clearly involves giving it to someone.

A more neutral verb in many contexts would be mover:

• Mueve la silla un poco a la derecha.

But pasar is also natural in Spain for this kind of small repositioning.

Pasa is the informal singular command form, used with tú.

It comes from the verb pasar:

• tú pasas = you move / you pass
• (tú) pasa = move / shift

For regular -ar verbs, the tú command is the same as the él/ella/usted present form:

• hablar → habla
• mirar → mira
• pasar → pasa

So here, Pasa la silla... means Move the chair... when speaking to one person informally.

Spanish usually leaves out subject pronouns unless they are needed for emphasis or clarity.

So instead of saying:

• Tú pasa la silla...

Spanish normally just says:

• Pasa la silla...

The verb form already tells you it is an informal command to you.

If you add tú, it can sound emphatic, contrastive, or unnatural in a simple everyday request.

In Spanish, articles are used more often than in English.

Here, la silla means:

• the chair

Even if English might sometimes say Move chair to the right in a very abbreviated style, normal Spanish needs the article:

• Pasa la silla...

Using just silla here would sound incomplete or unnatural.

The definite article la is used because the chair is understood to be a specific one in the situation.

Yes. Un poco literally means a little.

In this sentence it modifies the action, so it means:

• a little
• slightly
• a bit

So Pasa la silla un poco a la derecha means:

• Move the chair a little to the right.

It makes the instruction more precise and often softer. Compare:

• Pasa la silla a la derecha. = Move the chair to the right.
• Pasa la silla un poco a la derecha. = Move the chair a little to the right.

Because Spanish normally uses the preposition a in this expression:

• a la derecha = to the right / on the right

So:

• mover algo a la derecha = to move something to the right

You generally cannot say just derecha on its own in this structure.

Some useful comparisons:

• a la derecha = to the right
• a la izquierda = to the left

This is the standard expression after verbs of movement or placement.

Yes, you could.

• a la derecha = to the right
• hacia la derecha = toward the right

In many everyday situations, both work. But there is a slight nuance:

• a la derecha sounds like the target position
• hacia la derecha emphasizes the direction of movement

In your sentence, a la derecha is the most normal and natural choice.

Yes, por favor is flexible in Spanish.

All of these are possible:

• Por favor, pasa la silla un poco a la derecha.
• Pasa, por favor, la silla un poco a la derecha.
• Pasa la silla un poco a la derecha, por favor.

Putting por favor at the end is very common and sounds natural.

It softens the command and makes it a polite request.

Grammatically, it is a command because it uses the imperative form pasa.

But in real use, with por favor, it functions as a polite request.

So although the structure is imperative, the tone is not necessarily harsh. In Spanish, it is very normal to use the imperative politely:

• Abre la ventana, por favor.
• Pasa la silla un poco a la derecha, por favor.

English often prefers Could you... ? or Can you... ?, but Spanish commonly uses the imperative plus por favor.

For many learners, mueve la silla is the safest and most broadly understandable option.

• Mueve la silla un poco a la derecha. = Move the chair a little to the right.

However, pasa la silla can sound natural in Spain, especially when you mean shift it over a bit.

A rough comparison:

• mover = move
• pasar = move/shift over, pass along
• correr = slide/shift

Depending on the region and context, a native speaker might prefer one verb over another. For a Spain Spanish context, pasa la silla is plausible and natural.

Because this is the normal spelling.

Pasa does not need a written accent. It is stressed naturally on the first syllable:

• PA-sa

Also, in writing, the tú command pasa looks exactly the same as the present-tense form:

• él/ella/usted pasa = he/she/you-formal moves
• (tú) pasa = move

Context tells you which meaning it has. In your sentence, the presence of por favor and the overall structure make it clear that this is a command/request.

Yes. If you wanted to address someone formally, you would say:

• Pase la silla un poco a la derecha, por favor.

Compare:

• Pasa... = informal singular (tú)
• Pase... = formal singular (usted)

This is an important difference in Spanish, especially in Spain, where tú is common with friends, family, children, and many informal situations, while usted is more formal or distant.

Yes. If the chair is already understood from context, you could say:

• Pásala un poco a la derecha, por favor.

Here:

• la = it referring to la silla

Notice the accent in Pásala. The accent is needed because when pronouns are attached to a command, the stress pattern changes, and Spanish spelling marks that.

Compare:

• Pasa la silla...
• Pásala...

Both are correct, but the second one is used when the object is already known.
