Para la entrevista, mi hermana eligió una blusa blanca y una rebeca gris.

Because para expresses purpose or intended use here: the clothes were chosen for the interview.

• para la entrevista = for the interview
• por la entrevista would more likely suggest something like because of the interview or due to the interview

So in this sentence, para is the natural choice because it tells us what the outfit was chosen for.

Spanish often uses the definite article more than English does. Here, la entrevista refers to a specific event that speaker and listener can identify: the interview.

So:

• para la entrevista = for the interview

Leaving out the article would sound incomplete or unnatural in this context.

The verb is elegir (to choose), and its preterite form for él/ella/usted is eligió.

This happens because elegir is a stem-changing verb, and in some forms the stem vowel changes:

• infinitive: elegir
• preterite:
  • yo elegí
  • tú elegiste
  • él/ella eligió
  • nosotros elegimos
  • vosotros elegisteis
  • ellos eligieron

So eligió is the correct past form for mi hermana.

Eligió is the preterite tense, which is used for a completed action in the past.

So:

• mi hermana eligió... = my sister chose...

The sentence describes one finished action: she picked those clothes for the interview. That is why the preterite is used instead of the imperfect.

The accent mark shows the correct stress: e-li-GIÓ.

It also helps distinguish the pronunciation and written form of the preterite ending. In Spanish, written accents are important and are not optional.

So you should write:

• eligió ✅
  not
• eligio ❌

In Spanish, adjectives often come after the noun, especially when they describe ordinary qualities such as color, size, or shape.

So:

• una blusa blanca = a white blouse
• una rebeca gris = a grey cardigan

This is one of the most common word-order differences from English.

Because Spanish adjectives must agree with the noun, but not all adjectives change in the same way.

• blusa is feminine singular, so blanco becomes blanca
• gris is an adjective that usually has the same form for masculine and feminine singular

Examples:

• camisa blanca
• pantalón blanco
• rebeca gris
• jersey gris

So blanca changes, but gris stays the same.

Spanish often repeats the article when listing separate items, especially when each noun has its own adjective.

So:

• una blusa blanca y una rebeca gris

sounds clear and natural.

You may sometimes see one article covering two nouns, but here repeating una is the most normal choice because the speaker is describing two distinct pieces of clothing.

In Spain, rebeca commonly means cardigan.

This is a very Spain-specific everyday word. In other Spanish-speaking countries, people may use other words more often, such as:

• cárdigan
• suéter
• chaqueta
• saco
  depending on the country and the exact garment

So if you are learning Spanish from Spain, rebeca is a useful word to know.

Not exactly.

• blusa usually means blouse, typically a woman’s top
• camisa usually means shirt

In many contexts, blusa suggests a more feminine garment, while camisa is a broader word and can refer to shirts for men or women depending on context.

So blusa is the best match here if the original meaning is blouse.

Yes. Spanish word order is flexible, and that version is also correct:

• Mi hermana eligió una blusa blanca y una rebeca gris para la entrevista.

Starting with Para la entrevista puts a little more emphasis on the occasion or purpose. It sets the scene first:

• For the interview, my sister chose...

Both versions are natural.

A simple pronunciation guide for Spain Spanish would be:

• rebeca → reh-BEH-ka
• blusa blanca → BLOO-sa BLAN-ka
• eligió → eh-lee-HYOH

A few helpful notes:

• b and v sound very similar in Spanish
• bl in blusa and blanca is pronounced smoothly together
• the stress in rebeca is on be
• the stress in eligió is on the last syllable because of the accent mark

Spanish often uses possessives like mi, tu, su to show whose person or thing it is.

So:

• mi hermana = my sister

You generally need mi here unless the relationship is already very clear from context and the sentence is structured differently. On its own, hermana would mean sister, but it would not clearly mean my sister.
