La denegación llega durante el período de prueba.

Yes. La is the feminine singular definite article, so la denegación means the denial or the refusal/rejection, depending on context.

Spanish uses the definite article more often than English does. Here, la denegación refers to a specific denial that is understood from the context, so the denial is natural.

Also, denegación is feminine, which is why the article is la, not el.

Not quite.

• denegación usually means an official or formal denial, refusal, or rejection, especially of a request, application, permission, benefit, etc.
• negación more often means negation or denial in a broader sense, including denying that something is true.

So denegación is a good word for administrative, legal, or bureaucratic contexts.

Examples:

• la denegación de una solicitud = the rejection of an application
• la negación de los hechos = the denial of the facts

Yes, llega literally means arrives or comes. But in Spanish, just like in English, verbs of movement can be used more abstractly.

Here, la denegación llega means something like:

• the denial arrives
• the denial comes through
• the denial is received

This is natural in Spanish when talking about a letter, a decision, a notice, or an official response.

So even though denegación is abstract, the idea is that the decision or notification reaches the person.

Llega is the present tense, third person singular, from llegar.

It can be used in several ways:

• for a present event: it arrives / is arriving
• for a general statement: it comes
• sometimes for a scheduled or narrative present

Without more context, the sentence could be:

• a general statement about when the denial comes
• part of a summary or explanation
• a present-tense narration

If you changed the tense, the meaning would shift:

• llegó = arrived
• ha llegado = has arrived

Durante means during, so it emphasizes that something happens within the span of a period of time.

• durante el período de prueba = during the probationary/trial period

If you used en, it could sometimes work in other contexts, but it would not express the same idea as clearly here.

Compare:

• durante el período de prueba = during the trial period
• en el período de prueba = in the trial period

Both can sometimes be understandable, but durante is the more precise and natural choice when you mean at some point within that time span.

Período de prueba means trial period or probationary period, depending on context.

A very literal breakdown is:

• período = period
• de prueba = of trial/testing

But in natural English, you would usually say:

• trial period
• probationary period
• sometimes testing period

In job-related contexts, período de prueba often means the time at the start of employment when the worker is being evaluated.

Because de prueba works here like a defining complement: it tells you what kind of period it is.

So:

• período de prueba = trial period
• literally, period of trial/testing

Spanish often uses de + noun where English might use an adjective or a compound noun.

Compare:

• coche de carreras = racing car
• sala de espera = waiting room
• período de prueba = trial period

Adding la would usually sound less natural here unless you meant a very specific prueba already mentioned before.

Because prueba is just the noun inside the prepositional phrase de prueba.

The main noun of the whole phrase is período, which is masculine:

• el período

The phrase de prueba only modifies período. It does not have to agree with it the way an adjective would.

So:

• el período de prueba not because prueba is masculine, but because período is masculine.

The accent marks show the stressed syllable.

• denegación is stressed on the last syllable: de-ne-ga-CIÓN
• período is stressed on the rí: pe-RÍ-o-do

For learners, the important thing is:

• -ción words almost always have the stress at the end and are written with an accent: información, decisión, denegación
• período is written with an accent to show that the stress falls earlier than you might otherwise expect

A useful note: both período and periodo are accepted spellings, with different stress patterns in pronunciation. Período is very common.

In most of Spain, ll in llega is pronounced the same as y. So llega sounds roughly like YE-ga.

A broad approximation for Spain would be:

• llega ≈ YE-ga

Depending on the region, the exact sound can vary a little, but for most learners it is enough to know that:

• ll and y are usually pronounced alike in modern Spanish

Yes, but the original order is the most neutral.

Standard order:

• La denegación llega durante el período de prueba.

You could move the time phrase for emphasis:

• Durante el período de prueba llega la denegación.

That version is grammatically correct, but it sounds more marked or literary, because it emphasizes during the trial period.

So if you are just making a plain statement, the original word order is the best choice.

Yes, fairly formal.

Words like:

• denegación
• período de prueba

are common in administrative, legal, HR, and official contexts.

In more everyday Spanish, people might choose simpler wording depending on what they mean. For example:

• La rechazaron durante el período de prueba.
• La respuesta negativa llegó durante el período de prueba.

But if the context is bureaucratic or official, the original sentence sounds very natural.
