El intérprete jurado se prepara para ofrecer interpretación jurada.

They are related, but they are different parts of speech:

• intérprete = interpreter (the person)
• interpretación = interpreting / interpretation (the activity or service)

So:

• El intérprete jurado = the sworn interpreter
• ofrecer interpretación jurada = to offer sworn interpreting

This is similar to English interpreter vs interpretation, although in natural English you might more often say interpreting services.

Here jurado / jurada means sworn or officially certified, especially in a legal or administrative sense.

So intérprete jurado is not a jury interpreter. It means an interpreter who is officially authorised to provide sworn interpreting.

The adjective changes form to match the noun:

• intérprete jurado → masculine
• intérprete jurada → feminine
• interpretación jurada → feminine, because interpretación is feminine

Because prepararse means to get ready / to prepare oneself.

• prepara = prepares something
• se prepara = gets ready / prepares himself, herself, themself

So in this sentence:

• El intérprete jurado se prepara = The sworn interpreter gets ready

If you said prepara without se, you would normally expect a direct object:

• Prepara los documentos = He/She prepares the documents

para + infinitive is a very common structure meaning in order to + verb or simply to + verb.

So:

• se prepara para ofrecer = gets ready to offer / prepares in order to offer

Other examples:

• Estudia para aprobar = He/She studies in order to pass
• Se reúne para hablar = He/She meets up to talk

Because Spanish often leaves out the article when talking about a service, activity, or thing in a general sense.

So:

• ofrecer interpretación jurada = to offer sworn interpreting / sworn interpreting services

This sounds general and natural.

If you used an article, it would sound more specific:

• ofrecer la interpretación jurada = to provide the sworn interpreting (for a specific case or event)

So the version without the article is the more general one.

Because adjectives in Spanish usually agree with the noun they describe in gender and number.

• intérprete here refers to a masculine person or uses the masculine form generically, so the adjective is jurado
• interpretación is feminine, so the adjective must be jurada

That gives:

• el intérprete jurado
• la interpretación jurada

A useful detail: intérprete itself does not change form for masculine/feminine:

• el intérprete jurado
• la intérprete jurada

Yes. Intérprete is a noun with the same form for both genders.

You show the gender with the article and adjective:

• el intérprete jurado = the male sworn interpreter
• la intérprete jurada = the female sworn interpreter

This is quite common in Spanish with certain professions and roles.

El is the masculine singular definite article, meaning the.

Here it can refer to:

• a specific sworn interpreter already known in context, or
• a whole professional type in a general statement

For example, Spanish often uses el/la + singular noun to talk about a class of people:

• El médico ayuda a sus pacientes = Doctors help their patients
• El intérprete jurado se prepara... = The sworn interpreter prepares...

So depending on context, it may mean the sworn interpreter or something closer to a sworn interpreter / the sworn interpreter as a professional figure.

Yes, especially because this is a technical or formal expression.

• intérprete jurado
• interpretación jurada

Both are established terms, and repeating them is not wrong. In formal or professional Spanish, this kind of repetition is often perfectly normal.

In more stylistic writing, someone might rephrase to avoid repetition, but here the repetition keeps the meaning precise.

Yes. Normally:

• interpretación = interpreting, usually spoken
• traducción = translation, usually written

So interpretación jurada refers to sworn interpreting, not sworn translation.

If it were about written documents, you would expect:

• traducción jurada = sworn translation

This distinction is very important in Spanish.

Two words here have written accents:

• intérprete
• interpretación

These accents show where the stress goes:

• intérprete → stress on tér
• interpretación → stress on the final ción

By contrast:

• jurado has no written accent, so it follows normal stress rules
• prepara also follows normal stress rules

The accent marks are important because they help distinguish the correct pronunciation and rhythm of the sentence.
