Mi hermano tiene hambre después de trabajar.

In Spanish, hunger is usually expressed with tener (to have), not with estar or ser.

So:

• tener hambre = to be hungry
• literally, it looks like to have hunger

This is one of several very common Spanish expressions:

• tener sed = to be thirsty
• tener sueño = to be sleepy
• tener miedo = to be afraid

So Mi hermano tiene hambre is the normal, natural way to say it.

Because tener hambre is a fixed expression. Spanish normally does not say tener la hambre here.

Compare:

• tiene hambre = he is hungry
• tiene sed = he is thirsty

Even though hambre is a noun, in this expression it appears without an article.

Yes, but it is less common in everyday speech than tiene hambre.

• tiene hambre = the most natural, everyday phrasing
• está hambriento = understandable, but often sounds stronger, more descriptive, or less neutral

In most normal situations, especially in Latin American Spanish, tener hambre is the safer and more common choice.

Mi means my, so mi hermano means my brother.

Spanish usually puts the possessive adjective before the noun:

• mi hermano = my brother
• mi casa = my house
• mi trabajo = my job

Using mi makes the relationship clear. Without it, hermano would just mean brother in a more general sense.

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

• tiene can mean he has or she has or you (formal) have
• here, mi hermano already tells us the subject, so él is unnecessary

So:

• Mi hermano tiene hambre = natural
• Él tiene hambre = also correct, but now él adds emphasis or contrast

For example:

• Mi hermana no tiene hambre, pero él tiene hambre.

Tiene is the present indicative form of tener.

In this sentence, the present tense can mean:

• what is true right now: My brother is hungry after working
• or something generally/habitually true: My brother gets hungry after working

Spanish present tense often covers both ideas, and context tells you which one is meant.

Because after después, Spanish uses de before a verb in the infinitive.

So:

• después de trabajar = after working
• literally, after of working

This is a very common structure:

• después de comer = after eating
• después de estudiar = after studying
• después de llegar = after arriving

Because in Spanish, when a verb comes after a preposition like de, it usually stays in the infinitive.

So:

• después de trabajar = after working

Not:

• después de trabaja
• después de trabajó

This is similar to English after working, where working is not the main conjugated verb of the sentence.

Yes, but that is a different structure.

Use después de + infinitive when the subject is understood or the same:

• Mi hermano tiene hambre después de trabajar.

Use después de que + conjugated verb when you want a full clause:

• Mi hermano tiene hambre después de que trabaja.
• Mi hermano tuvo hambre después de que trabajó.

In many everyday cases, después de + infinitive is shorter and more natural.

The h in Spanish is silent.

So hambre is pronounced roughly like AHM-breh.

A few helpful notes:

• the h is not pronounced
• the stress is on the first syllable: HAM-bre
• the r is a soft single Spanish r, not a strong rolled rr

The accent mark shows where the stress goes: des-pués.

Without the accent, standard Spanish stress rules would suggest a different pronunciation. The written accent tells you clearly that the stress falls on the last syllable.

So you pronounce it roughly like:

• des-PWES

The accent is part of the correct spelling and should always be written: después.

Yes. Spanish word order is flexible here.

These are both natural:

• Mi hermano tiene hambre después de trabajar.
• Después de trabajar, mi hermano tiene hambre.

The second version puts more focus on after working. The meaning stays basically the same.

It is standard Spanish and sounds natural across the Spanish-speaking world, including Latin America and Spain.

Nothing in this sentence is especially regional:

• mi hermano
• tener hambre
• después de trabajar

These are all very common, neutral forms.
