La capacitación aumenta la capacidad y el rendimiento.

Yes, they are related, but they mean different things:

• capacitación = training, instruction, or skill development
• capacidad = capacity, ability, or capability

So in this sentence:

• La capacitación = the training
• la capacidad = the capacity/ability

This is a very common point of confusion for English speakers because both words come from the same root idea.

Spanish often uses the definite article more than English does.

So La capacitación literally looks like The training, but in many contexts it can still be translated naturally as just Training.

Spanish commonly uses articles with general concepts, abstract nouns, and subjects of sentences:

• La educación es importante.
• La práctica ayuda.
• La capacitación aumenta...

In English, we often drop the in these kinds of general statements, but Spanish often keeps it.

Because the subject is singular: La capacitación.

• La capacitación = singular
• so the verb is aumenta = increases

If the subject were plural, then the verb would be plural:

• Las capacitaciones aumentan... = Training programs increase...

So the verb agrees with capacitación, not with capacidad y rendimiento.

Because the sentence is talking about two different nouns, and they have different grammatical genders:

• la capacidad → feminine
• el rendimiento → masculine

Since one is feminine and the other is masculine, each one needs its own article.

That is why you get:

• la capacidad y el rendimiento

If both nouns had the same article, Spanish can sometimes drop the second one, but here it cannot because the genders are different.

In this sentence, rendimiento most naturally means performance, output, or productivity, depending on context.

Common possibilities:

• in work/business: performance or productivity
• in school: performance
• in technical contexts: efficiency or output

So la capacidad y el rendimiento suggests both:

• a person’s or system’s ability/capacity
• and its performance/results

Yes. Capacitación is very common in Latin America, especially in:

• workplace language
• HR
• education
• professional development
• government or institutional contexts

It often refers to organized training meant to improve skills.

A related word is entrenamiento, but that is often more associated with:

• sports training
• physical training
• practical training in some contexts

In professional or corporate settings, capacitación is often the more natural choice.

The accent mark shows which syllable is stressed.

capacitación is pronounced roughly like:

ca-pa-ci-ta-CIÓN

The last syllable is stressed: -ción.

Without the accent mark, Spanish pronunciation rules would suggest a different stress pattern, so the written accent is necessary.

Also, many nouns ending in -ción have this same pattern:

• educación
• información
• formación
• capacitación

A simple pronunciation guide is:

lah kah-pah-see-tah-SYON ow-MEN-tah lah kah-pah-see-DAD ee el ren-dee-MYEN-toh

A few notes for Latin American Spanish:

• c before i in capacitación and capacidad sounds like s
• y becomes ee before a word starting with i? Actually here it stays y because the next word starts with e, not i
• stress:
  • capacitaCIÓN
  • auMENta
  • capaciDAD
  • rendiMIENto

Spanish normally uses y for and.

It only changes to e before words that begin with an i sound:

• padres e hijos
• economía e industria

But el rendimiento starts with an e sound, not an i sound, so it stays:

• la capacidad y el rendimiento

Yes, depending on style and context. Some possible alternatives are:

• mejora = improves
• incrementa = increases
• eleva = raises
• fortalece = strengthens

For example:

• La capacitación mejora la capacidad y el rendimiento.
• La capacitación incrementa la capacidad y el rendimiento.

But aumenta is very straightforward and neutral. It clearly expresses the idea that training causes both things to go up.

Yes, Spanish word order is somewhat flexible, although this version is very natural:

• La capacitación aumenta la capacidad y el rendimiento.

You could also say something like:

• La capacitación aumenta el rendimiento y la capacidad.

That changes the order of the two objects, but not the basic meaning.

You could also restructure the sentence more dramatically:

• La capacidad y el rendimiento aumentan con la capacitación.

That means roughly the same thing, but now la capacidad y el rendimiento are the subject, so the verb changes to aumentan.

So yes, the word order can change, but the grammar has to change with it.
