Priorizar permite rendir mejor.

In Spanish, an infinitive can act like a noun or a general activity.

So priorizar here means something like prioritising / to prioritise in a general sense, not I prioritise or you prioritise.

That makes Priorizar permite rendir mejor a general statement, similar to:

• Comer bien ayuda. = Eating well helps.
• Dormir suficiente es importante. = Sleeping enough is important.

If you used a conjugated form, the meaning would become specific:

• Priorizo... = I prioritise...
• Priorizas... = You prioritise...

Here, the sentence is talking about the idea or habit of prioritising in general.

The subject is priorizar.

Even though priorizar is an infinitive, it can still function as the subject of the verb:

• Priorizar → subject
• permite → main verb

So the structure is basically:

• Prioritising allows...

This is very common in Spanish. Infinitives often behave like nouns.

Because permitir is followed directly by an infinitive when it means to allow / enable someone to do something, especially when the doer is general or unspecified.

So:

• permitir + infinitive

Examples:

• Esto permite ahorrar tiempo. = This allows you/one to save time.
• Descansar permite trabajar mejor. = Resting allows you/one to work better.

You only add an indirect object if you want to say who is allowed to do it:

• Esto te permite rendir mejor. = This allows you to perform better.
• La empresa les permite trabajar desde casa. = The company allows them to work from home.

So in your sentence, no person is mentioned, so rendir comes directly after permite.

Yes, rendir can mean different things depending on context.

Common meanings include:

• to yield / produce
• to perform
• to surrender (especially as rendirse, the reflexive form)

In rendir mejor, it means to perform better, especially in contexts like:

• work
• study
• productivity
• sport
• mental performance

Examples:

• Duermo mejor y rindo más. = I sleep better and perform more effectively.
• Los estudiantes rinden mejor por la mañana. = Students perform better in the morning.

So here it has nothing to do with surrendering.

Here mejor is an adverb meaning better, modifying the verb rendir.

• rendir mejor = to perform better

Compare:

• mejor = better
• bien = well

So:

• rendir bien = to perform well
• rendir mejor = to perform better

Mejora is usually a noun (improvement) or a verb form from mejorar:

• una mejora = an improvement
• mejora = he/she/it improves or imperative improve

And más bien usually means something like rather or more accurately, so it does not fit here.

Yes, in a sense the subject is left general and understood.

Spanish often leaves the doer unspecified in general statements. In English, you might translate that as:

• you
• one
• people
• or just use a gerund structure like prioritising allows better performance

In this sentence, rendir does not state exactly who performs better. It just means that, in general, prioritising helps a person perform better.

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

• Priorizar te permite rendir mejor. = Prioritising allows you to perform better.
• Priorizar nos permite rendir mejor. = Prioritising allows us to perform better.

Yes, but it means something slightly different.

• rendir mejor = to perform better
  Focus: quality, effectiveness
• rendir más = to perform more / be more productive
  Focus: quantity, output

Depending on context, both can work, but they are not exactly the same.

Examples:

• Con descanso, rindes mejor. = With rest, you perform better.
• Con descanso, rindes más. = With rest, you get more done / produce more.

So mejor is about improved performance, not necessarily increased amount.

Because Spanish often uses the bare infinitive directly for general statements.

So priorizar by itself is perfectly natural as the subject.

You can sometimes see el + infinitive, but that structure is more noun-like and often more formal, literary, or stylistically marked:

• El priorizar demasiado puede ser agotador.

That is possible, but in everyday Spanish, the simple infinitive is usually more natural here:

• Priorizar permite rendir mejor.

Yes, it is natural, especially in contexts like:

• productivity
• self-help
• workplace advice
• study techniques
• time management

It sounds concise and slightly formal or motivational, which is common in written Spanish.

Very natural alternatives in Spain might be:

• Priorizar te ayuda a rendir mejor.
• Saber priorizar permite rendir mejor.
• Si priorizas, rindes mejor.

Your original sentence is grammatically correct and natural.

It is pronounced roughly as:

• prio-ri-ZAR

The stress falls on the last syllable: -zar.

That is because verbs ending in -ar and written without an accent mark are normally stressed on the last syllable in the infinitive.

A rough English-friendly approximation is:

• pree-oh-ree-THAR in much of Spain

In most of Spain, z is pronounced like the th in think, so:

• priorizar → pree-oh-ree-THAR

In Latin America, it would usually sound more like pree-oh-ree-SAR.

Yes, and that is a very common alternative.

Compare:

• Priorizar permite rendir mejor.
• Priorizar ayuda a rendir mejor.

Both are correct, but the nuance is slightly different:

• permite = allows, makes possible, enables
• ayuda a = helps

So permite can sound a bit stronger or more formal, while ayuda a may sound slightly more conversational.

Another very natural option is:

• Priorizar hace que rindas mejor.

But that changes the structure, because now the second verb is conjugated (rindas) instead of staying in the infinitive.
