Perquè, Ja Que, Com Que, and Car | Catalan Grammar

Catalan does not have a single mechanical translation for English because. Perquè gives a neutral reason, ja que treats the reason as available or easy to accept, com que normally places that reason before the consequence, and car adds a written, elevated explanation. All four link clauses, but they package the cause differently in the conversation.

The basic decision

Connector	Usual information status	Typical position	Register
perquè	neutral answer to “why?”	usually after the main clause	neutral
ja que	known, visible, or readily accepted reason	before or after	neutral; common in careful speech and writing
com que	reason used as the starting point	normally first	neutral
car	speaker's explanatory justification	after the statement	(formal/literary)

No hem anat a la platja perquè bufava massa vent.

We didn't go to the beach because it was too windy.

Ja que demà fas festa, podríem dinar plegats.

Since you have tomorrow off, we could have lunch together.

Com que no trobàvem cap taxi, vam tornar a peu.

Since we couldn't find a taxi, we walked back.

Cal ajornar la votació, car encara falta l'informe jurídic. (formal/literary)

The vote must be postponed, for the legal report is still missing.

💡

Ask what the cause is doing in the discourse. If it simply answers per què?, choose perquè. If it is the shared premise from which the rest follows, ja que or initial com que often fits better.

Perquè: the neutral cause

Perquè introduces the cause of an event or decision. It normally follows the clause it explains and takes the indicative when the speaker presents the cause as factual. Unlike English because, it is written as one word and carries a grave accent: perquè. The question phrase per què is two words; see because and why.

He tancat la finestra perquè entrava fum del carrer.

I closed the window because smoke was coming in from the street.

La Núria no contesta perquè està fent una entrevista.

Núria isn't answering because she's in an interview.

Negation reveals scope. In the first sentence below, the reason for not calling is tiredness. In the second, the speaker denies that tiredness was the reason; perhaps there was another reason. Intonation and a pause make the second reading clearer.

No et vaig trucar perquè estava esgotada.

I didn't call you because I was exhausted. — tiredness caused the non-call.

No et vaig trucar perquè estigués enfadada; em vaig quedar sense bateria.

I didn't call you because I was angry; my battery died. — anger is rejected as the explanation.

The subjunctive in the rejected-cause pattern marks a cause that the speaker does not endorse as fact. This is a focused contrast, not a reason to put every negative sentence into the subjunctive. The ordinary factual cause still uses the indicative.

Ja que: a reason treated as given

Ja que is close to since/given that. It tells the listener, “we can accept this premise, so here is what follows.” The reason may be previously mentioned, obvious in the situation, or simply presented as uncontroversial. It can occur first or last; initial position is particularly natural when the reason frames a suggestion or inference.

Ja que ja tens el mapa obert, busca-hi una benzinera.

Since you already have the map open, look for a petrol station on it.

Podem començar sense ell, ja que ens ha avisat que arribarà tard.

We can start without him, since he told us he would arrive late.

Compare the minimal pair. Perquè supplies new causal information; ja que presents the same fact as the basis for a practical conclusion.

He obert el mapa perquè no sabia com arribar-hi.

I opened the map because I didn't know how to get there.

Ja que no saps com arribar-hi, obre el mapa de la ruta.

Since you don't know how to get there, open the route map.

The clitic hi remains attached to its verb according to ordinary clitic rules; the conjunction does not move it. In an embedded sentence, ja que can introduce a reason inside what someone said:

La directora ha dit que, ja que el projector no funciona, farem la reunió a l'altra sala.

The headteacher said that, since the projector isn't working, we'll hold the meeting in the other room.

Com que: make the cause the point of departure

Com que normally introduces a causal clause before the main clause. The initial clause sets the scene; the consequence then feels expected. English as can do this, but English learners should not translate the two words separately: causal com que is a fixed connector.

Com que l'ascensor estava espatllat, hem pujat els sis pisos per l'escala.

As the lift was broken, we walked up all six floors.

Com que no me'n recordava, ho he apuntat al calendari.

Since I couldn't remember it, I wrote it in the calendar.

Putting a comma after the initial causal clause makes the boundary visible. Final com que is possible in marked conversational afterthoughts, but it is not the neutral learner choice. Use final perquè instead.

Perquè plovia, ens vam quedar a casa.

Because it was raining, we stayed home. — grammatical, but less neutral than initial com que.

Com que plovia, ens vam quedar a casa.

As it was raining, we stayed home. — natural scene-setting order.

This is not merely word order. Initial com que signals that the cause is the discourse frame, whereas final perquè more readily answers a request for an explanation.

Car: an elevated explanatory “for”

Car introduces an explanation that justifies the preceding statement. It is productive in formal essays, institutional prose, or deliberately literary narration, but unusual in spontaneous everyday Central Catalan. In ordinary conversation, choose perquè or ja que. Car is not the noun carn and does not take que.

No podem donar l'expedient per tancat, car resten dues al·legacions per resoldre. (formal)

We cannot consider the case closed, for two objections remain to be resolved.

Va decidir no despertar-la, car dormia profundament. (literary)

He decided not to wake her, for she was sleeping deeply.

Car normally follows the claim it explains and is separated by a comma. Beginning a casual reply with it can sound theatrical. Its use is understood across Catalan-speaking territories; the decisive difference is register, not region. Standard Valencian follows the same distribution.

A natural dialogue

—Per què has canviat la reserva? —Perquè dissabte l'Arnau treballa. Com que diumenge tots tenim festa, l'he passada a diumenge. —Doncs, ja que hi serem tots, reservaré una taula més gran.

—Why did you change the booking? —Because Arnau works on Saturday. Since we're all off on Sunday, I moved it to Sunday. —Well, since we'll all be there, I'll book a bigger table.

The dialogue shows three distinct jobs: perquè directly answers per què; com que frames the consequence; ja que turns shared information into a new proposal.

Punctuation and regional perspective

A causal clause after the main clause usually has no comma when it is essential to the explanation: No vinc perquè estic malalt. Initial subordinate clauses normally take a comma: Com que estic malalt, no vinc. Parenthetical or afterthought explanations may be set off with commas. Punctuation reflects information structure, not a ban on a particular connector.

These connectors are standard in Central, Valencian, Balearic, Northwestern, Northern, and Alguerese Catalan. Pronunciation and local frequency vary, but learners do not need a different regional grammar here. Puix que is a possible (formal/archaic) causal connector in older or elevated texts; it is not a neutral replacement in present-day conversation.

Short correction task

Correct the connector or punctuation, then compare the answers.

Com que no hi havia cobertura vam enviar el missatge més tard.
No he vingut per què tenia febre.
Ja que no trobo les claus, perquè trucaré al manyà.

Com que no hi havia cobertura, vam enviar el missatge més tard.

Since there was no signal, we sent the message later. — add the boundary comma.

No he vingut perquè tenia febre.

I didn't come because I had a fever. — causal perquè is one word.

Ja que no trobo les claus, trucaré al manyà.

Since I can't find the keys, I'll call the locksmith. — do not stack perquè after an initial causal frame.

Common Mistakes

❌ No sortim per què està nevant.

Incorrect — per què is interrogative; this clause states a cause.

✅ No sortim perquè està nevant.

We're not going out because it's snowing.

❌ Com que el tren va amb retard agafarem un cafè.

Incorrect punctuation — the initial framing clause should be followed by a comma.

✅ Com que el tren va amb retard, agafarem un cafè.

Since the train is delayed, we'll get a coffee.

❌ Ens n'anem, car que és tard.

Incorrect — car is itself a conjunction and is not followed by que.

✅ Ens n'anem perquè és tard.

We're leaving because it's late. — neutral conversation; formal prose could use car without que.

⚠️ Perquè no quedava pa, vaig baixar a comprar-ne.

Marked rather than ungrammatical — initial perquè is possible in a focused explanation, but it is not the neutral scene-setting choice.

✅ Com que no quedava pa, vaig baixar a comprar-ne.

Since there was no bread left, I went down to buy some.

Key Takeaways

Use perquè for a neutral reason, especially as the direct answer to per què?
Use com que to put the cause first as the frame for the consequence, and normally follow that initial clause with a comma.
Use ja que when the reason is already shared, visible, or treated as an accepted premise.
Reserve car for formal or literary explanation; in ordinary conversation, prefer perquè or ja que.

💡

Do not choose solely from an English dictionary gloss. Perquè explains, com que frames, ja que builds on an accepted premise, and car justifies in an elevated written voice.
