Sin cita previa, no puedo renovar el pasaporte en el ayuntamiento.

Sin cita previa sets the condition first: without a prior appointment. Spanish often puts this kind of phrase at the beginning to give the context before the main statement.

You could also say:

No puedo renovar el pasaporte en el ayuntamiento sin cita previa.

That means the same thing. The version with Sin cita previa first sounds a bit more emphatic, as if the speaker is highlighting the requirement.

Sin means without.

So:

• sin = without
• con = with

Examples:

• sin dinero = without money
• sin ayuda = without help
• sin cita previa = without a prior appointment

In Spanish, after sin, it is very common to leave out the article when speaking generally.

So:

• sin cita previa = without an appointment / without prior appointment

This sounds natural and idiomatic, especially in administrative language.

You could say sin una cita previa, but it is less natural here and sounds more specific or less fixed as an expression. In Spain, sin cita previa is a very common set phrase you see on signs, websites, and official notices.

Cita means appointment.
Previa means prior or previous.

Together, cita previa means an appointment booked in advance.

In Spain, this is a very common expression for appointments with:

• doctors
• government offices
• police stations
• town halls
• immigration offices

So cita previa is not just any meeting; it usually means an official scheduled appointment.

In Spanish, adjectives usually come after the noun, so:

• cita previa
• pasaporte nuevo
• oficina pública

That is the normal order.

You may sometimes see previa cita in more formal or bureaucratic language, but cita previa is the standard everyday expression in Spain.

No puedo renovar means I cannot renew.

Here, no negates the verb puedo:

• puedo = I can
• no puedo = I cannot / I’m not able to

If you say puedo no renovar, that usually means I may choose not to renew or I can refrain from renewing, which is a different idea.

So:

• no puedo renovar = I can’t renew
• puedo no renovar = I can choose not to renew

Because it comes after puedo, from the verb poder (to be able to / can).

In Spanish, after a conjugated modal-type verb like poder, the next verb normally stays in the infinitive:

• puedo renovar = I can renew
• quiero renovar = I want to renew
• necesito renovar = I need to renew

So:

• puedo is the conjugated verb
• renovar stays in the infinitive

Yes. Renovar is the normal verb for renewing documents such as:

• renovar el pasaporte = renew the passport
• renovar el DNI
• renovar el carné de conducir = renew the driving licence

It is also used for other things, like subscriptions or contracts:

• renovar una suscripción
• renovar un contrato

Spanish often uses the definite article more than English does.

So Spanish says:

• renovar el pasaporte
• cerrar la puerta
• lavarse las manos

Even when English might say renew my passport or just renew passport in certain contexts, Spanish usually prefers the article with the noun.

Here, el pasaporte means the passport, but in natural English we would often translate it as my passport if the context makes that obvious.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

• puedo already tells you the subject is yo = I

So:

• (Yo) no puedo renovar el pasaporte...

Both are correct, but Spanish usually prefers to omit yo unless you want emphasis or contrast.

For example:

• Yo no puedo, pero ella sí.
  I can’t, but she can.

Ayuntamiento usually means town hall or city hall, and it can also refer to the local council as an institution.

So en el ayuntamiento means at the town hall / at city hall.

Depending on context, it may refer to:

• the building
• the office there
• the local administration in general

In practical English, at the town hall is usually the best translation.

Because Spanish only has two mandatory contractions with el:

• a + el = al
• de + el = del

But:

• en + el stays en el
• con + el stays con el
• por + el stays por el

So en el ayuntamiento is exactly what you should expect.

Yes, you could say that.

• renovar el pasaporte = renew the passport
• renovar mi pasaporte = renew my passport

Both are correct. Spanish often prefers el pasaporte when ownership is obvious from the context, while English more often uses my passport.

So Spanish may sound less possessive than English in these situations.

It can suggest either, depending on context.

No puedo renovar el pasaporte... literally means I can’t renew the passport..., but in real use it often means:

• I am not able to
• I’m not allowed to
• it isn’t possible for me to

Because of sin cita previa, the most natural interpretation is that the office requires an appointment, so the speaker cannot do it without one.

Yes. A very natural alternative is:

No puedo renovar el pasaporte en el ayuntamiento sin cita previa.

This has the same meaning. Spanish word order is often more flexible than English.

Compare:

• Sin cita previa, no puedo renovar el pasaporte en el ayuntamiento.
• No puedo renovar el pasaporte en el ayuntamiento sin cita previa.

The first one emphasizes the condition first. The second one sounds slightly more neutral.

Yes, very much so.

In Spain, cita previa is a very common expression in official and everyday administrative contexts. You often see it on government websites and notices such as:

• Solo con cita previa
• Atención con cita previa
• Es necesario pedir cita previa

A learner of Spanish in Spain will hear and see this phrase a lot.
