Para desayunar, a veces quiero un croissant y un café con leche.

Para + infinitive is a very common Spanish pattern meaning for doing something or to do something.

So para desayunar literally means for having breakfast and is a very natural way to say for breakfast in this kind of sentence.

• para desayunar = for breakfast / to have for breakfast
• para el desayuno = for the breakfast meal

Both can work, but para desayunar sounds very idiomatic here.

Por desayunar would not fit this meaning. Por usually expresses things like cause, movement through, exchange, or duration, not purpose in this structure.

They are different parts of speech:

• desayunar = to have breakfast (verb)
• desayuno = breakfast (noun)

In this sentence, Spanish uses the verb because it follows para:

• para desayunar = for having breakfast

If you used the noun, you would say something like:

• para el desayuno = for breakfast

So the sentence uses the verbal version, not the noun version.

A veces means sometimes.

It is a fixed expression in Spanish, and it is normally written as two words:

• a
  • veces

You just learn it as a set phrase. It does not take an article, so not las veces here.

Examples:

• A veces estudio por la mañana.
• A veces quiero un croissant.

Yes, its position is flexible.

The sentence:

• Para desayunar, a veces quiero un croissant y un café con leche.

is natural, but you could also say:

• A veces, para desayunar, quiero un croissant y un café con leche.
• A veces quiero un croissant y un café con leche para desayunar.

All of these are understandable. The original version puts para desayunar first to set the context, then adds a veces.

So the word order is about emphasis and rhythm, not a change in core meaning.

Not necessarily. Quiero means I want, but in everyday Spanish it can also sound like I feel like or I’d like, depending on context.

Here it sounds fine because the speaker is talking about a usual preference:

• a veces quiero... = sometimes I want / feel like...

In a café or restaurant, though, some speakers might choose a softer form, such as:

• me gustaría
• quisiera
• me apetece (very common in Spain for I feel like)

So quiero is grammatically correct and natural here, but it is not the only option.

Because Spanish normally repeats the article with each singular countable item in a list when they are separate things:

• un croissant y un café con leche

This clearly means one croissant and one café con leche.

Repeating the article is the normal and natural choice here. It marks each item as its own separate thing.

You might hear article omission in some contexts, but in this sentence un croissant y un café con leche is the most natural form.

Why?

• croissant is a countable item, so un croissant sounds normal.
• café con leche in this context means one serving / one cup, so un café con leche is also natural.

Without the article, the sentence sounds more generic or less polished. For a learner, using un here is the safest and most idiomatic choice.

Because Spanish often omits the article when naming ingredients or standard combinations.

So:

• café con leche = coffee with milk
• pan con tomate = bread with tomato
• té con limón = tea with lemon

Using con la leche would suggest a specific milk already identified in the conversation, which is not the idea here.

So café con leche is the normal fixed expression.

Yes, croissant is very common in Spain, especially in cafés and bakeries.

It is normally treated as masculine:

• un croissant

There is also a fully adapted Spanish spelling:

• cruasán

Both exist, but croissant is extremely common in real life in Spain.

Because the stress falls on the last syllable: ca-FÉ.

In Spanish spelling, words ending in a vowel, n, or s are normally stressed on the second-to-last syllable unless there is a written accent. Since café ends in a vowel but is stressed on the final syllable, it needs the accent mark.

So the accent shows the correct pronunciation and follows the spelling rules.

Because Para desayunar is an introductory phrase.

In Spanish, short introductory phrases are often followed by a comma, especially when they set the scene or context for the rest of the sentence:

• Para desayunar, ...

The comma helps readability and makes the sentence sound more natural in writing.

You may sometimes see short phrases without a comma in informal writing, but here the comma is perfectly normal and stylistically good.
