Demà el meu pare em portarà a l'estació en cotxe.

In Catalan, possessives are very often used together with the definite article: el meu pare, la meva mare, el meu cotxe.

So where English says my father, Catalan normally says the my father literally, though of course that is just how Catalan grammar works and should not be translated word for word.

With close family members, body parts, and many everyday nouns, the article is especially common.
So el meu pare is the normal standard form.

Em means to me or me here. It is a weak pronoun (clitic pronoun).

In el meu pare em portarà, the idea is that the father will take me somewhere.

Catalan often uses these short pronouns before the verb:

• em = me / to me
• et = you
• el / la = him / her / it
• ens = us
• us = you plural
• els / les = them

So:

• Em portarà = He will take me
• Et portarà = He will take you

In a normal affirmative sentence with a finite verb, weak pronouns usually go before the verb in Catalan.

So:

• em portarà
• et dirà
• ens ajudarà

Pronouns are attached after the verb mainly with:

• infinitives: portar-me
• gerunds: portant-me
• affirmative imperatives: porta'm

Since portarà is a future-tense finite verb, em comes before it: em portarà.

Catalan often leaves out subject pronouns when the verb ending already shows who the subject is.

Portarà already tells you it is he/she/it will take. Because of that, ell is not necessary.

So Catalan commonly says:

• Demà el meu pare em portarà...

rather than:

• Demà ell em portarà...

You can include ell for emphasis or contrast, but it is not normally needed.

Portarà is the future tense of portar.

The infinitive is portar. To form the future in Catalan, you normally add future endings directly to the infinitive:

• portaré = I will take
• portaràs = you will take
• portarà = he/she will take
• portarem = we will take
• portareu = you plural will take
• portaran = they will take

So em portarà means he will take me.

The accent marks show stress.

• demà is stressed on the last syllable
• portarà is also stressed on the last syllable

These accents help with pronunciation and sometimes distinguish words that might otherwise look similar.

Very roughly:

• demà ≈ de-MA
• portarà ≈ por-ta-RA

This is a contraction.

• a = to
• la estació would be awkward, so Catalan contracts it to l'estació

So:

• a + l'estació = to the station

The l' is the shortened form of the definite article before a vowel.

You will often see:

• l'estació
• l'escola
• l'amic
• l'hotel

Because the two phrases express different relationships.

• a l'estació shows destination: to the station
• en cotxe shows means of transport: by car / in a car

In Catalan, transport is often expressed with en:

• en cotxe = by car
• en tren = by train
• en avió = by plane

So the sentence uses:

• a for where someone is going
• en for how they are going

En cotxe is the normal general expression for by car.

When you are talking about the means of transport in a general way, Catalan usually does not use the article:

• en cotxe
• en tren
• en autobús

If you say en el cotxe, that usually means in the car, referring to a specific car rather than just the method of travel.

So:

• Vaig en cotxe = I go by car
• Vaig en el cotxe del meu pare = I am going in my father's car

Yes. Demà is quite flexible.

You can say:

• Demà el meu pare em portarà a l'estació en cotxe.
• El meu pare em portarà a l'estació en cotxe demà.

Putting demà at the beginning is very natural and gives it a little prominence, like setting the time frame first.

Beginning the sentence with a time expression is extremely common in Catalan.

Yes, portar can mean carry, but it can also mean take someone/something somewhere, depending on context.

In this sentence, portar means something like take or drive someone to a place.

Catalan often uses portar in situations where English uses take:

• Et porto a casa. = I’ll take you home.
• Em portarà a l'estació. = He’ll take me to the station.

In some varieties of Catalan, you may also hear dur with a similar meaning.

You change the possessive phrase and/or the pronoun.

Examples:

• Demà la meva mare em portarà a l'estació en cotxe.
  = my mother

• Demà els meus pares em portaran a l'estació en cotxe.
  = my parents

• Demà el meu pare ens portarà a l'estació en cotxe.
  = my father will take us

Notice:

• la meva mare = feminine singular
• els meus pares = masculine plural
• ens = us
• portaran agrees with plural subject els meus pares

Estació is roughly pronounced es-ta-see-O.

The ending -ció is very common in Catalan and usually corresponds to English -tion:

• informació
• nació
• estació

The stress falls on the last syllable because of the accent: estació.

So the final part sounds roughly like see-O, not like English shən.
