Casi nunca desayuno con prisa.

Casi nunca means almost never. It softens nunca, which means never.

So:

• Nunca desayuno con prisa = I never eat breakfast in a hurry.
• Casi nunca desayuno con prisa = I almost never eat breakfast in a hurry.

It suggests that it happens very rarely, but not absolutely never.

Here, desayuno is a verb, from desayunar (to have breakfast / to eat breakfast).

It is the first-person singular present form:

• yo desayuno = I have breakfast

This form looks exactly like the noun desayuno (breakfast), so context tells you which one it is.

In Casi nunca desayuno con prisa, it is clearly a verb because it is the action of the sentence.

Spanish often leaves out subject pronouns when the verb form already makes the subject clear.

• desayuno already means I have breakfast
• so yo is not necessary

You could say Yo casi nunca desayuno con prisa, but adding yo would usually give extra emphasis, such as contrast:

• Yo casi nunca desayuno con prisa, pero mi hermano sí.
  I almost never eat breakfast in a hurry, but my brother does.

Without emphasis, leaving out yo is the most natural choice.

In Spanish, adverbs like casi nunca, siempre, a menudo, and nunca often go before the verb.

So:

• Casi nunca desayuno con prisa is the normal word order.

You may also hear slight variations in longer sentences, but for a simple sentence like this, placing casi nunca before the verb is the standard and most natural pattern.

Literally, con prisa means with haste or with hurry, but in natural English it means in a hurry.

Yes, it is a very common Spanish expression. It is used to describe doing something quickly because you do not have much time.

Examples:

• Voy con prisa. = I’m in a hurry.
• Habla con prisa. = He/She speaks in a hurried way.
• Desayuno con prisa. = I eat breakfast in a hurry.

So this is a normal idiomatic phrase, not a strange literal construction.

Spanish often prefers natural expressions like con prisa instead of a more formal adverb.

Compare:

• Desayuno con prisa = I eat breakfast in a hurry.
• Desayuno rápidamente = I eat breakfast quickly.

Both are grammatical, but they are not exactly the same in feeling:

• con prisa focuses on being rushed
• rápidamente focuses more on speed

So con prisa is especially good when the idea is I’m rushed, not just I’m fast.

Because con prisa is a fixed expression. Spanish often omits the article in common prepositional phrases.

So you say:

• con prisa = in a hurry

not normally:

• con la prisa in this meaning

con la prisa can exist, but it usually means something more specific, like because of the rush or with the hurry/stress of the situation, not the general expression in a hurry.

Yes, desayuno is in the present tense, but in this sentence it expresses a habit or usual behavior, not just what is happening right now.

So the sentence means something like:

• I almost never eat breakfast in a hurry.
• It is almost never the case that I rush breakfast.

This is a very common use of the Spanish present tense: describing routines and general habits.

Not really, at least not with the same natural meaning.

For almost never, Spanish normally uses:

• casi nunca

Using casi no is possible in some contexts, but it usually works differently and can sound incomplete or unnatural here.

So for this sentence, the best choice is:

• Casi nunca desayuno con prisa.

That is the standard way to say I almost never eat breakfast in a hurry.

Yes. In Spain, desayunar is the normal and very natural verb for to have breakfast / to eat breakfast.

So:

• Desayuno a las siete. = I have breakfast at seven.

This is more natural than trying to say something like tomo el desayuno in everyday speech.

In Spain, using desayunar directly is simple and idiomatic.

Yes, in Spain you may also hear con prisas, especially in everyday speech.

Both exist:

• con prisa
• con prisas

But con prisa is the more basic, standard expression and fits this sentence perfectly.

So Casi nunca desayuno con prisa is completely natural. If you hear con prisas, especially in Spain, that is also normal speech, just slightly different in style.
