El pase permite entrar.

In this sentence, pase is a noun, not a verb. It usually means something like a pass, entry pass, ticket, or permit—something that gives you access.

In Spain, pase is very commonly used for:

• an access pass
• a backstage pass
• a visitor’s pass
• a ticket/pass that lets you in

So here it refers to the thing that gives permission to enter.

Because pase is a masculine noun in this meaning, so it takes el.

• el pase
• not la pase

This is something you usually just have to learn with the noun. The ending -e does not automatically tell you whether a noun is masculine or feminine, so pase must simply be learned as masculine.

Permite is the third-person singular present tense of permitir.

So it matches the subject el pase:

• el pase permite = the pass allows / permits

A quick pattern:

• yo permito
• tú permites
• él/ella/usted permite

Since el pase is a singular subject, permite is the correct form.

Because after verbs like permitir, Spanish often uses an infinitive to say what action is allowed.

Structure:

• permitir + infinitive

So:

• permite entrar = allows entry / allows one to enter

Other similar examples:

• permite acceder = allows access
• permite salir = allows you to leave
• permite usar el sistema = allows you to use the system

This is very normal Spanish.

Because Spanish does not always need to state who the action applies to, especially in general statements.

El pase permite entrar is a general, neutral way of saying that the pass gives permission to enter. The person is understood from context.

If you want to make it more explicit, you could say:

• El pase te permite entrar. = The pass allows you to enter.
• El pase le permite entrar. = The pass allows him/her/you (formal) to enter.

Without te / le / nos, the sentence stays more general and is very natural on signs, notices, or simple descriptions.

Because after permitir, Spanish normally uses the infinitive directly:

• permitir entrar
• permitir pasar
• permitir acceder

So a is not needed here.

English learners often expect something like permit to enter, but Spanish works differently in this structure.

Compare:

• Te permite entrar.
  Not: Te permite a entrar.

Yes, absolutely. It is a complete sentence.

Grammatically:

• El pase = subject
• permite = verb
• entrar = infinitive complement

The idea of who enters is left general or understood from context. That is very common in Spanish, especially in concise statements like instructions, notices, or descriptions.

It has the feel of:

• The pass allows entry
• The pass lets you in

Yes. That is also correct.

The difference is:

• El pase permite entrar = general, neutral, impersonal
• El pase te permite entrar = specifically the pass allows you to enter

So if you are talking directly to one person, te may sound more natural.
If it is a general statement on a sign or in a description, the version without te is very common.

Yes, and it is very natural.

Compare the nuance:

• El pase permite entrar = the pass authorises/allows entry
• Con el pase puedes entrar = with the pass, you can enter

The first sounds a bit more formal or informational.
The second is slightly more direct and conversational.

Both are correct; the choice depends on style and context.

Yes. Pase can also be a verb form of pasar, for example:

• Espero que pase pronto. = I hope it happens soon.
• Pase usted. = Come in. / Go ahead.

But in El pase permite entrar, it is clearly a noun because:

• it comes after el
• it is the subject of the sentence

So here it definitely means pass, not a verb.

In standard Spain Spanish, pase is pronounced approximately PAH-seh, with the stress on the first syllable:

• PA-se

The s is a normal s sound.
The final e is clearly pronounced, unlike in English.

So do not say something like pass in English; pronounce both syllables:

• PA-se

Yes, it sounds very natural in formal or semi-formal contexts such as:

• museums
• events
• private areas
• transport or access systems
• security or reception desks

It has a concise, official style. Spanish often uses short statements like this in practical contexts.

Possible similar phrases:

• La tarjeta permite entrar.
• La acreditación permite el acceso.
• Este pase permite entrar al recinto.

So the sentence is short, but very idiomatic.
