A las once suelo tener hambre, pero hoy he desayunado tarde.

A las once means at eleven o’clock.

In Spanish, the usual pattern for clock time is:

• a la
  • singular hour: a la una
• a las
  • plural hour: a las dos, a las once

So A las once is the normal way to say at eleven.

Suelo comes from the verb soler, which means to usually do something or to tend to do something.

So:

• suelo tener hambre = I usually get hungry / I’m usually hungry

A very important point: soler is normally followed by an infinitive.

Examples:

• Suelo comer a las dos. = I usually eat at two.
• Solemos salir los sábados. = We usually go out on Saturdays.

Because the speaker is talking about a habit, not just a current state.

• Tengo hambre = I am hungry
• Suelo tener hambre = I usually get hungry / I’m usually hungry

In this sentence, the speaker is contrasting a normal routine with what is different today:

• A las once suelo tener hambre = At eleven I’m usually hungry
• pero hoy... = but today...

So soler helps express what normally happens.

Because Spanish uses the verb tener for many physical states where English uses to be.

So:

• tener hambre = to be hungry
• tener sed = to be thirsty
• tener sueño = to be sleepy
• tener frío = to be cold

This is a fixed and very common Spanish pattern.
So tengo hambre literally looks like I have hunger, but it means I am hungry.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

• suelo clearly means I usually
• he desayunado clearly means I have eaten breakfast

So yo is unnecessary unless you want emphasis or contrast.

For example:

• Yo he desayunado tarde, pero él no. = I had breakfast late, but he didn’t.

In your sentence, leaving out yo sounds natural.

This is a very common Spain Spanish usage.

He desayunado is the present perfect:

• he
  • past participle
• he desayunado = I have had breakfast

In Spain, the present perfect is often used for actions that happened today or in a time period connected to the present:

• Hoy he desayunado tarde. = Today I had breakfast late / I have had breakfast late today.

In many parts of Latin America, people would more often say:

• Hoy desayuné tarde.

Both are grammatically correct, but he desayunado strongly matches standard usage in Spain.

It is the pretérito perfecto, formed with:

• present tense of haber
• past participle of the main verb

Here:

• he = I have
• desayunado = had breakfast / breakfasted

The infinitive is desayunar.
For -ar verbs, the past participle ends in -ado:

• desayunar → desayunado
• hablar → hablado
• llegar → llegado

So:

• he desayunado = I have had breakfast

Hoy means today, and it helps explain why the speaker uses a different tense and makes a contrast with the usual routine.

The sentence structure is:

• Normally: A las once suelo tener hambre
• Today: pero hoy he desayunado tarde

So hoy marks this as an exception to the usual pattern.

Desayunar means to have breakfast / to eat breakfast.

It can be used without saying what exactly you ate:

• He desayunado tarde. = I had breakfast late.

You can also add more information if you want:

• He desayunado tostadas. = I had toast for breakfast.
• He desayunado en casa. = I had breakfast at home.

So in your sentence, no object is needed because the important idea is the time of breakfast, not the food itself.

Here tarde means late.

So:

• he desayunado tarde = I had breakfast late

Be careful: tarde can also mean afternoon, depending on context.

Examples:

• por la tarde = in the afternoon
• llego tarde = I arrive late

In your sentence, because it comes after a verb, it clearly means late.

Pero means but and introduces a contrast.

The contrast is:

• Usually at eleven I’m hungry
• but today I had breakfast late

The idea is that because breakfast happened later than usual, the normal hunger at eleven may not happen today.

So pero connects the usual pattern with the special situation today.

Literally, it means at eleven. But in real life, it can often sound a bit flexible, like around eleven or by eleven, depending on context.

Spanish often uses exact clock expressions in a natural, everyday way without meaning the precise minute.

So the sentence suggests:

• Eleven is normally the time when I start feeling hungry

not necessarily exactly 11:00:00.

Yes: hoy he desayunado tarde is very typical of Spain Spanish.

In Spain, speakers often use the present perfect for actions that happened today, this morning, this week, etc.

Examples:

• Hoy he comido pronto.
• Esta mañana he salido temprano.

In much of Latin America, the preterite is often more common in the same situations:

• Hoy desayuné tarde.

So if you are learning Spanish from Spain, this sentence is a very natural model.
