El expediente sancionador indica el organismo sancionador.

Because it is modifying two different nouns:

• expediente sancionador = the sanctioning/disciplinary case file or proceedings
• organismo sancionador = the sanctioning body/authority

In both places, sancionador is an adjective meaning something like that imposes a sanction or related to sanctions. It is not repetitive by mistake; it is doing a job in each noun phrase.

No. That is a very common confusion.

• sancionador = sanctioning, punitive, imposing sanctions
• sancionado = sanctioned, punished, fined

So:

• organismo sancionador = the body that gives the sanction
• organismo sancionado = the body that has been sanctioned

That -dor ending often suggests the doer of an action, like an agent.

This is a formal legal/administrative expression, especially common in Spain.

Expediente can mean a file, record, or case dossier. In administrative language, expediente sancionador refers to the official proceedings or file opened in order to investigate and possibly impose an administrative penalty.

So this is not just a random document. It often refers to the whole official case file or procedure.

Because grammatical gender in Spanish is not determined only by the ending.

Expediente is a masculine noun:

• el expediente

Since it is masculine singular, the adjective must also be masculine singular:

• el expediente sancionador

This is something you often just have to learn with the noun.

Because there are two separate noun phrases:

• El expediente sancionador = the subject
• el organismo sancionador = the direct object

Structure:

• El expediente sancionador / indica / el organismo sancionador
• subject / verb / object

You need the article with both because both are definite noun phrases: the case file and the sanctioning body.

Literally, yes, indica means indicates. But in English, especially in legal or administrative contexts, you might translate it more naturally as:

• states
• specifies
• identifies
• sets out

So depending on context, El expediente sancionador indica el organismo sancionador could be understood as The case file identifies/states which authority is imposing the sanction.

Yes. It follows a very standard Spanish order:

• Subject: El expediente sancionador
• Verb: indica
• Object: el organismo sancionador

That is a normal subject + verb + object sentence. Because it is formal written Spanish, it sounds a bit dense, but the structure itself is straightforward.

No. Even though the words look similar, that would be a false friend here.

In this context, organismo means:

• body
• agency
• authority
• institution

So organismo sancionador is something like the sanctioning authority or the body imposing the penalty, not a biological organism.

It is definitely formal, administrative, and legal in tone.

Words like:

• expediente
• sancionador
• organismo

are very typical of official documents, notifications, and legal procedures in Spain.

In everyday conversation, a person would probably say something simpler, depending on the situation, such as:

• El documento dice qué organismo pone la sanción.
• Aquí se indica qué autoridad te sanciona.

Adjectives in Spanish agree with the noun in gender and number.

Here both nouns are masculine singular:

• el expediente → masculine singular
• el organismo → masculine singular

So the adjective is also masculine singular in both cases:

• sancionador

If the noun were feminine, it would change:

• la autoridad sancionadora

If plural:

• los organismos sancionadores

Yes. In legal Spanish, you may also see terms like:

• órgano sancionador
• autoridad sancionadora

These are often very close in meaning. The exact choice depends on the type of institution and the legal text.

For a learner, the important thing is that all of them refer to the authority or body that has the power to impose the sanction.

Because Spanish often uses a noun + adjective structure where English might prefer something longer.

So instead of saying something like:

• expediente de sanción

Spanish often uses:

• expediente sancionador

This is especially common in formal and legal language. The adjective sancionador packages the idea neatly into one fixed expression. In practice, expediente sancionador is the standard legal phrase you should learn as a chunk.
