La práctica libre permite marcar el paso.

In Spanish, it is very common to use the definite article with nouns, even when English would often leave it out.

So la práctica libre is the natural way to say free practice or open practice as a general activity/session.

Compare:

• La práctica libre es útil. = Free practice is useful.
• Necesitamos más práctica. = We need more practice.

Both are possible in Spanish, but with a full noun phrase like práctica libre, the article often sounds more complete and natural.

Práctica is a feminine noun, so it takes:

• la práctica
• una práctica

This is partly because nouns ending in -a are often feminine, though that is only a general pattern, not an absolute rule.

Also, be careful: práctica can be a noun, while práctico/práctica can also be an adjective.

Examples:

• La práctica ayuda mucho. = Practice helps a lot.
• Es una idea práctica. = It’s a practical idea.

So in your sentence, práctica is a noun: practice.

In Spanish, adjectives usually come after the noun.

So:

• práctica libre = free practice
• tiempo libre = free time
• entrada libre = free admission

Putting the adjective after the noun is the normal word order. If you moved libre before the noun, it would sound unusual here and could change the emphasis or sound unnatural.

Yes. Adjectives in Spanish usually agree in gender and number with the noun they describe.

Here:

• práctica = feminine singular
• libre = singular form

Libre is one of those adjectives that has the same form for masculine and feminine singular:

• el ejercicio libre
• la práctica libre

But in the plural, it changes:

• las prácticas libres
• los ejercicios libres

So it is agreeing, even though the singular masculine and feminine forms look the same.

Because the subject is singular:

• La práctica libre = singular

So the verb must also be singular:

• La práctica libre permite...

If the subject were plural, then you would use permiten:

• Las prácticas libres permiten marcar el paso.

This is just normal subject-verb agreement.

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

So it can mean:

• he/she allows
• it allows
• you allow (formal usted)

In this sentence, it means it allows, because the subject is la práctica libre.

Mini-conjugation of permitir in the present:

• yo permito
• tú permites
• él/ella/usted permite
• nosotros permitimos
• vosotros permitís
• ellos/ellas/ustedes permiten

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

Structure:

• permitir + infinitive

So:

• permite marcar = allows [someone] to mark/set...

Other examples:

• Me permite entrar. = It allows me to enter.
• Esto permite aprender más rápido. = This allows [you/one] to learn faster.

This is very similar to English allow + to + verb, although Spanish usually just uses the infinitive directly after permitir.

Good question. Spanish can leave that idea unstated when it is general or obvious from context.

So:

• La práctica libre permite marcar el paso.

can mean something like:

• Free practice allows you/one/people to set the pace.

If you want to specify who is allowed, you can add an indirect object pronoun:

• La práctica libre te permite marcar el paso. = Free practice allows you to set the pace.
• La práctica libre nos permite marcar el paso. = Free practice allows us to set the pace.

Without a pronoun, the sentence sounds more general.

Because marcar el paso is a set expression, and it normally uses the definite article.

Spanish often uses the article in expressions where English may not.

Other examples:

• tener razón = to be right
• dar el paso = to take the step
• seguir el ritmo = to keep the rhythm/pace

So el is not random here; it belongs naturally to the phrase marcar el paso.

Yes, it can be.

Literally, it means something like to mark the step. Depending on context, it can be used more idiomatically to mean things like:

• to set the pace
• to keep the rhythm
• in military contexts, to march in place / mark time

So the exact nuance depends on the context where the sentence appears. Even if the translation has already been given to you, it is useful to know that this expression is not always interpreted purely word-for-word.

No. After permitir, you do not use de before the infinitive.

Correct:

• permite marcar

Incorrect:

• permite de marcar

This is a common mistake for English speakers because learners often expect an extra linking word. But in Spanish, permitir + infinitive is the normal structure.

They are related, but they are different parts of speech:

• práctica = noun = practice
• practicar = verb = to practise / to practice

Examples:

• La práctica es importante. = Practice is important.
• Quiero practicar más. = I want to practise more.

In your sentence, práctica is the noun, not the verb.

Because the stress falls on the syllable prác-: PRÁC-ti-ca.

Spanish spelling rules require a written accent here to show the correct stress pattern.

This accent is important because it distinguishes the pronunciation clearly. Native speakers already know the word, but for learners it is especially helpful because it shows that the stress is not on -ti- or -ca.

So pronounce it roughly as:

• PRAC-tee-ka

with the stress on the first syllable.
