Haver de + infinitive is Catalan's central personal construction for obligation: He de marxar “I have to leave.” Unlike Spanish haber de, it is not literary or old-fashioned. It is normal in contemporary speech and writing across the Catalan-speaking territories.
The construction can also present an expected, scheduled, or strongly anticipated action: El tren ha d'arribar a les sis. Its exact force comes from context. The finite form of haver locates the obligation in time and agrees with the subject; the infinitive names the required or expected action.
Present-tense formation
Use a personal form of haver, then de, then an infinitive. Before a vowel or silent h, de elides to d'.
| Person | Form | Example |
|---|---|---|
| jo | he de / haig de | he d'arribar |
| tu | has de | has de respondre |
| ell/ella/vostè | ha de | ha d'esperar |
| nosaltres | hem de | hem de decidir |
| vosaltres | heu de | heu d'entrar |
| ells/elles/vostès | han de | han de sortir |
He de passar per la farmàcia abans que tanquin.
I have to stop by the pharmacy before they close.
Has d'enviar el formulari abans de divendres al migdia.
You have to send the form before noon on Friday.
Hem de parlar amb els veïns abans de començar les obres.
We need to speak to the neighbors before starting the work.
He de is the broad, highly portable first-person form. Haig de is also standard and very common (regional: especially Central Catalan). The added -g belongs to this obligation construction in the present; as a perfect auxiliary, use he: he arribat, not haig arribat.
Stress falls on the finite auxiliary and on the lexical infinitive in their normal positions. Keep the apostrophe in d'anar, d'obrir, d'haver. The spelling tinc que may resemble Spanish tengo que, but it is not the neutral standard Catalan pattern.
Personal obligation and necessity
The grammatical subject of haver is the person or thing to which the requirement applies. This makes the construction more personal than cal + infinitive.
Els nous llogaters han de canviar el titular del contracte de la llum.
The new tenants have to change the name on the electricity contract.
No heu de deixar les bicicletes davant de la sortida d'emergència.
You must not leave bicycles in front of the emergency exit.
Negated no haver de is context-sensitive. In rules and instructions it commonly means must not (No heu d'entrar), but in a permissive context it can also mean “do not have to” (No has de venir si no vols). When absence of necessity must be unmistakable, use no cal: No cal que vingueu demà “You don't need to come tomorrow.”
The source of the obligation may be external (El reglament diu que heu de...), practical (Hem de comprar pa), or self-imposed (He de dormir més). Catalan does not require a different auxiliary for each source. Tone and context do much of the work.
Expectation, schedule, and planned action
With inanimate subjects or timetabled events, literal obligation may fade into expectation. English often translates this as “is due to,” “is supposed to,” or a plain future.
El paquet ha d'arribar entre dilluns i dimarts.
The parcel is due to arrive between Monday and Tuesday.
La nova biblioteca ha d'obrir al públic aquesta tardor.
The new library is expected to open to the public this autumn.
The same form can support an inference: Han de ser gairebé les deu “It must be almost ten.” The page on Deure for Probability develops the more specialized inferential pattern. Do not assume that English “must” always means obligation; ask whether someone is required to act or the speaker is drawing a conclusion.
An expected action is not automatically asserted as fact. El paquet ha d'arribar demà presents the delivery as scheduled or predicted, not as already true. This illustrates a general Catalan principle: tense form, viewpoint, and assertion status work together; a dictionary translation of have to cannot determine the reading by itself.
Moving the obligation through time
Conjugate haver, not the lexical infinitive. Different tenses add important aspectual contrasts:
| Form | Example | Usual value |
|---|---|---|
| present | he de trucar | current/future requirement |
| imperfect | havia de trucar | requirement or plan viewed from the past; fulfillment left open |
| periphrastic past | vaig haver de trucar | bounded necessity that arose and was dealt with |
| future | hauré de trucar | future requirement |
| conditional | hauria de trucar | advice, desirable action, or hypothetical requirement |
| present subjunctive | hagi de trucar | obligation inside a nonasserted dependent frame |
Havia d'agafar el tren de les set, però em vaig adormir.
I was supposed to catch the seven o'clock train, but I overslept.
Com que es va espatllar l'ascensor, vam haver de pujar sis pisos a peu.
Since the lift broke down, we had to walk up six floors.
Hauríeu de reservar taula; els dissabtes sempre està ple.
You should book a table; it's always full on Saturdays.
The imperfect havia de looks forward from a past reference point and does not say whether the plan was completed. The periphrastic past vaig haver de presents the necessity as a bounded past episode and normally implies that the required action occurred. Do not confuse vaig haver de pujar with a near-future anar a construction: here vaig + haver is the Catalan periphrastic past and de pujar completes haver de.
Mood follows the surrounding clause, not a memorized “obligation trigger”:
Dubto que hàgim de repetir tota la prova.
I doubt that we'll have to repeat the whole test.
The matrix dubto que makes the obligation nonasserted and selects hàgim. In an independent assertion, use hem de repetir. The obligation meaning alone does not force the subjunctive.
Weak-pronoun placement
With a weak pronoun belonging to the infinitive, Catalan normally allows climbing before finite haver or attachment to the infinitive. Keep a whole pronoun cluster together.
L'he de trucar abans de les cinc.
I have to call her before five.
He de trucar-la abans de les cinc.
I have to call her before five.
No els ho hem d'explicar fins que ho confirmi la direcció.
We mustn't explain it to them until management confirms it.
Both positions in the first pair are standard. With elision, write l'he and d'explicar correctly. Never insert the pronoun between de and the infinitive as a free word. See Pronoun Climbing for larger clusters.
The contrast with caldre and tenir que
| Construction | Subject profile | Standard/register status |
|---|---|---|
| haver de + infinitive | personal: the subject bears the obligation | neutral standard |
| cal + infinitive | generic or situation-centered necessity | neutral standard |
| cal que + subjunctive | impersonal frame; dependent verb identifies the actor | neutral standard |
| tenir que + infinitive | personal | (informal, under Spanish contact) widespread in some speech, but avoided in formal standard Catalan |
Per entrar al laboratori, heu de portar ulleres de protecció.
To enter the laboratory, you have to wear safety glasses.
Per entrar al laboratori, cal portar ulleres de protecció.
To enter the laboratory, safety glasses must be worn.
The first addresses a specific group. The second formulates a general requirement. In edited speech and writing, replace contact-induced teniu que portar with heu de portar. This is a real register distinction: describing the colloquial form does not make it the recommended neutral model.
Mini-dialogue: a changed appointment
—Demà he d'anar al dentista a les quatre; em pots cobrir l'última hora?
—I have to go to the dentist at four tomorrow; can you cover my last hour?
—Sí, però m'hauràs d'enviar les claus de l'aula abans de dinar.
—Yes, but you'll have to send me the classroom keys before lunch.
—Cap problema. Te les havia de donar avui, però me les he deixades a casa.
—No problem. I was supposed to give them to you today, but I left them at home.
The dialogue moves from a current obligation to a future requirement and then to an unfulfilled past plan. The clusters m', te les, and me les precede the relevant finite verbs.
Common Mistakes
1. Copying Spanish tener que.
❌ Tinc que renovar el passaport abans del viatge.
Nonstandard in formal Catalan — tenir que is a widespread Spanish-contact form.
✅ He de renovar el passaport abans del viatge.
I have to renew my passport before the trip.
2. Omitting or changing the preposition.
❌ Hem que avisar el propietari avui mateix.
Incorrect — personal haver takes de, not que.
✅ Hem d'avisar el propietari avui mateix.
We have to notify the landlord today.
3. Conjugating the lexical verb as well.
❌ Ella ha de presenta el certificat original.
Incorrect — the second verb must be the infinitive presentar.
✅ Ella ha de presentar el certificat original.
She has to present the original certificate.
4. Using no cal when prohibition is intended.
❌ No cal que entreu en aquesta sala: està prohibit.
Wrong meaning — no cal says that entering is unnecessary, not that it is forbidden.
✅ No heu d'entrar en aquesta sala: està prohibit.
You must not enter this room: it is forbidden.
5. Using a progressive or participle after de.
❌ Els tècnics han d'estan revisant la instal·lació.
Incorrect — haver de takes an infinitive, not a conjugated progressive.
✅ Els tècnics han de revisar la instal·lació.
The technicians have to inspect the installation.
Key Takeaways
- Use personal he/has/ha/hem/heu/han + de/d' + infinitive for neutral standard obligation.
- He de is broadly shared; haig de is also standard and especially common in Central Catalan.
- Havia de leaves fulfillment open, whereas va haver de usually presents an actual bounded necessity.
- Pronouns may climb before haver or attach to the infinitive: l'he de veure / he de veure'l.
- Prefer haver de over contact-induced tenir que in neutral and formal Catalan; use no cal for unambiguous “there is no need.”
