El fiscal llegó.

El is the masculine singular definite article, meaning the.

In Spanish, it is very common to use the definite article with nouns where English also uses the. Here, el fiscal means the prosecutor.

Because fiscal is a singular masculine noun in this sentence, it takes el.

In this sentence, fiscal is masculine: el fiscal.

A lot of nouns ending in -al are masculine, but the main thing to learn is the article together with the noun:

• el fiscal = the male prosecutor / prosecutor
• la fiscal = the female prosecutor

So fiscal can refer to either a man or a woman, and the article shows the gender.

Llegó is the third-person singular preterite form of the verb llegar.

That means it can mean:

• he arrived
• she arrived
• it arrived
• you arrived (formal usted)

In El fiscal llegó, the subject is el fiscal, so llegó means the prosecutor arrived.

The accent mark in llegó shows the stress: lle-GÓ.

It is also important because it distinguishes this form from other forms:

• llego = I arrive / I am arriving (present)
• llegó = he/she/it arrived (preterite)

So the accent is not optional. It changes both pronunciation and meaning.

Yes, you can also say Llegó el fiscal.

Both are correct:

• El fiscal llegó
• Llegó el fiscal

Spanish word order is often more flexible than English.
The version with the subject first, El fiscal llegó, is neutral and straightforward.
The version Llegó el fiscal can sound a bit more like The prosecutor arrived with slight focus on the arrival or on introducing who it was.

No. In fact, you normally would not say Él llegó here unless the subject were already clear from context and you specifically meant he arrived.

Spanish often leaves out subject pronouns because the verb form already gives information about the person and number. In this sentence, the noun el fiscal already tells us who arrived, so no pronoun is needed.

In Spain Spanish, fiscal is pronounced approximately fee-SKAL.

A few pronunciation points:

• fi sounds like fee
• sc before a sounds like sk
• the stress is on the last syllable: fis-CAL

So the whole sentence is roughly: el fee-SKAL yeh-GOH

In most of Spain, ll is usually pronounced like the y sound in yes, so llegó sounds roughly like yeh-GOH.

The stress is on the last syllable because of the accent mark:

• lle-GÓ

Depending on the region, the exact ll sound can vary slightly, but yeh-GOH is a good practical approximation for learners.

Both are possible in Spanish, but they are used differently.

• llegó = preterite, a completed past action
• ha llegado = present perfect, often connected to the present in some way

In Spain Spanish, the present perfect is often used for recent past actions connected to the current time period, but the preterite is also very common for simple completed events.

So El fiscal llegó is a normal way to say that the arrival happened as a completed event in the past.

Yes. Fiscal can have different meanings depending on context.

As a noun, it often means prosecutor.
As an adjective, it can mean fiscal, financial, or tax-related, as in:

• política fiscal = fiscal policy

But in El fiscal llegó, fiscal is clearly being used as a noun because it follows the article el.

Sometimes, depending on context, English might translate llegó as came rather than arrived.

The core meaning of llegar is to arrive / to reach a place.
English may choose came in more natural translation if the destination is understood from context.

Still, grammatically, llegó is the past form of llegar, whose basic meaning is arrived.

The dictionary form is llegar, which means to arrive.

When learning Spanish verbs, it is useful to connect the conjugated form to the infinitive:

• llegar = to arrive
• llegó = he/she/it arrived

That helps you recognize tense and person more easily.

The sentence itself is neutral. It is neither especially formal nor informal.

What may feel formal is the word fiscal, because it refers to a legal profession. But grammatically, El fiscal llegó is just a standard, natural sentence.
