El pare sempre tanca la porta quan surt de casa.

In Catalan, you normally use the definite article with family members in many everyday contexts, especially in central varieties:

• el pare = dad / the father
• la mare = mum / the mother

This is very natural in Catalan, even where English would often just say Dad or my dad.

So El pare sempre tanca la porta... is a normal way to say Dad always closes the door...

It can mean both, depending on context and tone.

• pare is the basic word for father
• In many contexts, el pare sounds perfectly natural as dad

So in this sentence, it could be understood as either:

• The father always closes the door when he leaves home
• Dad always closes the door when he leaves home

The exact English choice depends on the context and the translation style.

Sempre means always, and it commonly goes before the verb in Catalan:

• sempre tanca = always closes

That word order is very normal. Catalan often places adverbs like sempre before the conjugated verb.

Compare:

• El pare sempre tanca la porta. = Dad always closes the door.

This is similar to English, where always often comes before the main verb.

Tanca is the 3rd person singular present indicative of tancar (to close / to shut).

So:

• jo tanco = I close
• tu tanques = you close
• ell/ella tanca = he/she closes

Here, el pare is he, so Catalan uses tanca.

Catalan usually does not need subject pronouns unless you want emphasis, contrast, or clarity.

Because tanca already shows the person and number, and because el pare is already the subject, adding ell would usually be unnecessary.

So Catalan naturally says:

• El pare sempre tanca la porta

not usually:

• El pare ell sempre tanca la porta

Catalan is a pro-drop language, like Spanish or Italian.

La porta means the door.

• porta = door
• la = the

So:

• tanca la porta = closes the door

This is straightforward. Catalan uses the definite article here just as English does.

Quan means when.

It introduces a time clause:

• quan surt de casa = when he leaves home

The verb surt is in the present indicative because the whole sentence describes a habitual action:

• He always closes the door when he leaves home

This is not about one specific future event, but about something that generally happens.

Surt is the 3rd person singular present indicative of sortir (to go out / to leave).

So:

• jo surto = I go out / I leave
• tu surts = you go out / you leave
• ell/ella surt = he/she goes out / leaves

In this sentence, surt refers back to el pare, so it means:

• when he leaves
• or more literally, when he goes out

Because sortir is the natural verb for going out or leaving a place.

• sortir de casa = to leave home / to go out of the house

English often uses leave in this kind of sentence, while Catalan commonly uses sortir.

So quan surt de casa is a very normal Catalan expression.

In Catalan, casa often appears without an article when it means home rather than a specific physical house.

So:

• de casa = from home
• a casa = home
• ser a casa = to be at home

If you say de la casa, it usually sounds more like from the house as a specific building, not the general idea of home.

That is why quan surt de casa is best understood as when he leaves home.

Yes. Casa can mean:

• house in some contexts
• home in many everyday expressions

In this sentence, de casa is much more naturally from home or leaving home, not just from the house in a purely physical sense.

It describes a habitual action, something that regularly happens.

The present tense in Catalan, just like in English, can express habits:

• El pare sempre tanca la porta quan surt de casa.
• Dad always closes the door when he leaves home.

So it is not necessarily happening right now. It means this is his usual behaviour.

Yes, depending on context.

Even though the sentence says el pare and not explicitly el meu pare, Catalan often uses the with close family members where English may prefer my.

So possible translations include:

• Dad always closes the door when he leaves home.
• My father always closes the door when he leaves home.
• The father always closes the door when he leaves home. — less likely in ordinary conversation unless the context is specific

The most natural English choice often depends on who is speaking and the situation.

A careful approximate pronunciation is:

el PA-rə SEM-prə TANG-kə lə POR-tə kwan surt də KA-zə

A few useful notes:

• pare sounds roughly like PA-rə
• sempre sounds roughly like SEM-prə
• tanca has a hard c sound: TANG-kə
• quan sounds like kwan
• surt has a short u, not like English sur
• casa often sounds like KA-zə in central Catalan

Pronunciation varies somewhat by dialect, but this gives a helpful starting point.

Yes, Catalan has some flexibility, but the original order is the most neutral and natural:

• El pare sempre tanca la porta quan surt de casa.

You could move some elements for emphasis, but that changes the focus:

• Quan surt de casa, el pare sempre tanca la porta.

This still means the same thing, but it gives more prominence to when he leaves home.

For a learner, the original sentence is the best model to follow.
