El ascenso depende del rendimiento.

Because the verb is depender de = to depend on.

So the full structure is:

• depender de algo = to depend on something
• depender de alguien = to depend on someone

In your sentence, de + el rendimiento becomes del rendimiento:

• depende de el rendimiento → depende del rendimiento

So del is not a different preposition choice; it is just the contraction of de + el.

Del is the mandatory contraction of de + el.

Examples:

• de el jefe → del jefe
• de el rendimiento → del rendimiento

So:

• depende del rendimiento = depends on the performance

Important:

• de + el = del
• but de + la does not contract:
  • depende de la experiencia

Spanish uses articles more often than English does.

Here, El ascenso usually refers to:

• a specific promotion already being discussed, or
• the idea of promotion in a general, natural noun phrase

In English, you might say:

• Promotion depends on performance or
• The promotion depends on performance

Spanish often prefers the article in cases like this:

• El éxito depende del esfuerzo.
• La salud depende de muchos factores.

So El ascenso sounds normal and natural.

In this sentence, ascenso most likely means promotion in a job or professional setting.

But ascenso can also mean:

• ascent
• rise
• upward movement

Examples:

• un ascenso en el trabajo = a promotion at work
• el ascenso de la montaña = the ascent of the mountain

So the meaning depends on context. In a workplace sentence like this one, learners should usually read ascenso as promotion.

Both can sometimes relate to advancement, but they are not always interchangeable.

In Latin American Spanish:

• ascenso is very common for job promotion
• promoción can mean several other things, such as:
  • advertising/promotion
  • a sale or special offer
  • a graduating class
  • promotion in some contexts, but often less precise here

So El ascenso depende del rendimiento sounds very natural for Promotion depends on performance.

If you say promoción, people may need more context.

Rendimiento often means performance, but its meaning can shift depending on context.

Common meanings include:

• work performance
• academic performance
• output/productivity
• efficiency
• yield/return

Examples:

• rendimiento laboral = work performance
• rendimiento académico = academic performance
• rendimiento del motor = engine performance
• rendimiento de una inversión = return on an investment

In your sentence, it most likely means job performance.

Because standard Spanish usually prefers native words like rendimiento or sometimes desempeño, depending on the region and context.

For workplace evaluation in Latin America, you may hear:

• rendimiento
• desempeño

Examples:

• El ascenso depende del desempeño.
• El ascenso depende del rendimiento.

Both can work, though the nuance may vary a little:

• desempeño often sounds like overall job performance
• rendimiento can emphasize output, results, or level of performance

Performancia is generally not the normal everyday choice in this kind of sentence.

Depende is the third-person singular present indicative of depender.

Conjugation:

• yo dependo
• tú dependes
• él/ella/usted depende

It is used because the sentence expresses a general truth or rule:

• El ascenso depende del rendimiento. = Promotion depends on performance.

This is not talking about one moment only; it states a general condition.

Yes, you could say Del rendimiento depende el ascenso, and it is grammatically correct.

The original order:

• El ascenso depende del rendimiento is the most neutral and straightforward.

The alternative:

• Del rendimiento depende el ascenso puts more emphasis on del rendimiento.

So both are correct, but the first one is more standard for a learner to use.

Because ascenso is a masculine noun, so it takes el.

• el ascenso

Many nouns ending in -o are masculine, and ascenso follows that common pattern.

Related forms:

• un ascenso = a promotion
• el ascenso = the promotion

As always, grammatical gender in Spanish is a property of the noun itself; it does not necessarily reflect biological gender.

Normally, no. Depende de rendimiento sounds incomplete or unnatural in standard Spanish.

You would usually say:

• depende del rendimiento
• depende de su rendimiento
• depende del rendimiento laboral
• depende del buen rendimiento

Spanish generally wants a determiner here:

• an article (el)
• a possessive (su)
• or some other modifier

So del rendimiento is the natural form.

You would replace del rendimiento with a possessive phrase:

• El ascenso depende de tu rendimiento. = The promotion depends on your performance.
• El ascenso depende de su rendimiento. = The promotion depends on his/her/your-formal performance.

Notice that there is no contraction here, because the word after de is not el:

• de tu rendimiento
• de su rendimiento

Only de + el becomes del.

They can overlap, and in many work contexts both are possible.

A useful learner-friendly distinction is:

• rendimiento = performance in terms of results, output, efficiency, productivity
• desempeño = performance in terms of how someone carries out their role or duties

So these can both sound natural:

• El ascenso depende del rendimiento.
• El ascenso depende del desempeño.

In many Latin American workplace contexts, desempeño is very common when talking about employee evaluations, while rendimiento can sound a bit more focused on measurable results.

A simple approximate pronunciation is:

el ah-SEN-so deh-PEN-de del ren-dee-MYEN-to

A few key points:

• ascenso is stressed on sen: as-CEN-so
• depende is stressed on pen: de-PEN-de
• rendimiento is stressed on mien: ren-di-MIEN-to
• the d in del and depende is usually softer than an English d
• the r in rendimiento is a light tap here, not a strong rolled rr

Yes. A very natural alternative is:

• Ascender depende del rendimiento.

But this version is less natural because ascender means to be promoted / to rise, and using an infinitive as the subject here sounds more abstract.

More natural alternatives would be:

• Que te asciendan depende de tu rendimiento. = Whether you get promoted depends on your performance.
• Te ascienden según tu rendimiento. = They promote you based on your performance.

Still, the original sentence with el ascenso is clear, formal, and very natural.
