Catalan has no obligatory verb ending meaning “I saw this,” “I inferred this,” or “someone told me this.” Instead, speakers build evidential meaning with modal verbs, impersonal predicates, reporting conditionals, prepositional source phrases, and lexical verbs. The choice matters: deu ser presents an inference, es veu que és commonly presents indirect information, and segons l'informe, és names the source.
English also lacks a fully grammaticalized evidential system, so the broad idea is familiar. The danger is treating “apparently,” “must,” and “reportedly” as interchangeable. Catalan makes different commitments about evidence and responsibility through ordinary syntax rather than through one special mood.
An evidential map
| Construction | Typical evidence | Speaker commitment | Register |
|---|---|---|---|
| deure + infinitive | inference from clues | fairly strong probability | neutral |
| sembla que | appearance or incomplete evidence | qualified | neutral |
| es veu que | hearsay or newly learned fact | distanced | neutral-informal |
| segons + source | explicit report | assigned to named source | all registers |
| reporting conditional | unconfirmed report | deliberately withheld | formal/journalistic |
The distinctions concern scope and attribution, not truth itself. A speaker may use segons l'informe for a fact they accept completely, or es veu que for a rumor they doubt.
Inference with deure + infinitive
Epistemic deure means that available clues support a conclusion. The tense of deure and the infinitive locate the inference in time. Present inference commonly uses deu + infinitive; inference about a completed event can use deu haver + participle.
Els llums estan apagats; ja deuen dormir.
The lights are off; they must already be asleep. (neutral inference)
La porta no ha estat forçada: el lladre devia tenir una clau.
The door was not forced; the thief must have had a key. (past inference)
No respon ningú. Deuen haver sortit a dinar.
Nobody is answering. They must have gone out for lunch. (inference about a completed event)
The bracketed structure is [EPIST deu [INF tenir una clau]], where deure scopes over the proposition “have a key.” It is not deontic obligation. Context normally distinguishes Ha de presentar el formulari avui (“must submit it,” obligation) from Deu ser al despatx (“must be in the office,” inference). The modality page treats this contrast in detail.
In careful standard Catalan, do not use the conditional deuria merely as a present probability marker under influence from Spanish debería de. Deu ser tard expresses a present inference. Hauria de ser aquí a les nou normally expresses expectation or obligation: “he should be here at nine.”
Appearance with semblar and regional parèixer
Sembla que profiles an appearance or tentative assessment rather than a deduction. An affirmative clause ordinarily takes the indicative when the proposition is presented as likely; negation or explicit rejection often favors the subjunctive because the proposition is not asserted.
Sembla que el tren arribarà amb vint minuts de retard.
It seems that the train will arrive twenty minutes late. (neutral)
No sembla que la incidència afecti els vols internacionals.
It does not seem that the incident affects international flights. (neutral-formal; nonasserted complement)
Pel que sembla, l'acord encara no està tancat.
Apparently, the agreement has not been finalized yet. (neutral)
(regional: Valencian) Parèixer is standard and productive: Pareix que plourà. It does not signal a different degree of evidence; it is a regional lexical choice. Sembla que is the broad Central Catalan baseline and is understood across varieties.
Do not confuse subject raising with an initial subject. In Sembla que falten dos documents, the finite complement que falten dos documents is the content of sembla; dos documents is the postverbal subject of falten. The sentence does not have que as a subject marker.
Reported discovery and hearsay with es veu que
Es veu que literally resembles “it is seen that,” but in contemporary speech it often means “apparently,” “it turns out,” or “I hear that.” It distances the information source without necessarily expressing doubt. It is especially common in informal and neutral conversation.
Es veu que han canviat l'hora de la visita i no ens han avisat.
Apparently they changed the appointment time and did not tell us. (neutral-informal)
—Per què és tancada la botiga? —Es veu que avui fan inventari.
‘Why is the shop closed?’ ‘Apparently they're taking inventory today.’ (informal dialogue)
Es veu que la Laia ja ho sabia, però no ens en va dir res.
Apparently Laia already knew, but she did not tell us anything about it. (informal)
The clitics in the last example remain obligatory according to their predicates: ho sabia resumes the reported fact, and en va dir marks the topic “about it.” An impersonal evidential phrase does not permit omission of argument clitics.
In a research paper, es veu que is usually too source-vague. Name the evidence: segons les dades, com mostra la figura 2, or d'acord amb l'estudi. In conversation, its vagueness can be socially useful because it avoids naming the person who supplied the news.
Explicit attribution with segons
Segons takes a noun phrase, pronoun, or clause-like reporting expression: segons la portaveu, segons ells, segons explica l'informe. It does not normally take a bare que complement.
Segons l'informe tècnic, l'esquerda no compromet l'estructura.
According to the technical report, the crack does not compromise the structure. (formal)
L'esquerda no compromet l'estructura, segons explica l'informe tècnic.
The crack does not compromise the structure, as the technical report explains. (reordered formal attribution)
Segons la Joana, la reunió es va ajornar perquè faltava documentació.
According to Joana, the meeting was postponed because documentation was missing. (neutral)
The initial version normally scopes over the full proposition. Final segons la Joana can sound like an afterthought but still attributes the whole statement. Ambiguity arises in Segons la Joana, van ajornar la reunió perquè faltava documentació: does Joana report both the postponement and its cause, or only the postponement? A precise version repeats the source relation: La Joana afirma que van ajornar la reunió i atribueix la decisió a la manca de documentació.
Punctuation follows information structure. A fronted source frame is normally followed by a comma. An integrated phrase such as Ho van fer segons les instruccions has no comma and means “in accordance with the instructions,” not necessarily “according to the instructions' claim.”
The reporting conditional
News and institutional prose use the conditional to attribute information that has not been independently confirmed: hauria dimitit, s'haurien reunit, hi hauria tres ferits. This is the (formal/journalistic) reporting conditional, not an unreal condition.
El director hauria presentat la dimissió aquest matí, segons fonts del consell.
The director reportedly submitted his resignation this morning, according to council sources. (formal/journalistic)
Les dues parts s'haurien reunit en secret abans de l'anunci.
The two sides reportedly met in secret before the announcement. (formal/journalistic; source withheld)
Segons Protecció Civil, hi ha tres carreteres tallades.
According to Civil Protection, three roads are closed. (formal; direct attribution is preferable when the source is known)
The conditional protects attribution boundaries, but it should not become a substitute for reporting. If the source is known, naming it is clearer and more accountable. Segons Protecció Civil, hi ha... openly assigns the statement; hi hauria... alone merely signals distance.
Neutral and reordered evidence frames
La comissió deu haver rebut ja les al·legacions.
The committee must already have received the objections. (neutral inference scope)
Les al·legacions, la comissió ja les deu haver rebut.
The objections—the committee must already have received them. (topic-fronted; spoken emphasis)
The reordered sentence requires les because les al·legacions is a detached object topic, not the subject. Modal scope remains over haver rebut. Treating every initial noun phrase as an English-style subject would erase the structure and produce the ungrammatical Les al·legacions, la comissió deu haver rebut.
Common Mistakes
❌ Deuria ser a casa perquè hi ha llum.
Nonstandard for the intended present inference in careful Catalan—use present 'deu ser'.
✅ Deu ser a casa perquè hi ha llum.
He must be at home because the light is on.
❌ Segons que el diari, demà hi haurà vaga.
Incorrect—'segons' takes the source noun phrase directly, without 'que'.
✅ Segons el diari, demà hi haurà vaga.
According to the newspaper, there will be a strike tomorrow.
❌ No sembla que el servei funciona amb normalitat.
Incorrect in the intended nonassertive reading—negated 'no sembla que' calls for the subjunctive 'funcioni'.
✅ No sembla que el servei funcioni amb normalitat.
It does not seem that the service is operating normally.
❌ Els resultats, els investigadors deuen haver publicat avui.
Incorrect—the fronted direct-object topic needs the resumptive clitic 'els'.
✅ Els resultats, els investigadors els deuen haver publicat avui.
The results—the researchers must have published them today.
Correction and source task
Improve these forms: (1) Segons que diu l'informe, no hi ha risc; (2) No sembla que vindran demà in a nonassertive reading; (3) Hi hauria quatre ferits when emergency services have directly confirmed the number.
- Segons diu l'informe, no hi ha risc or Segons l'informe, no hi ha risc.
- No sembla que vinguin demà.
- Segons els serveis d'emergències, hi ha quatre ferits. Once a named authority directly confirms the information, an attribution phrase plus indicative is clearer than an unsupported reporting conditional.
Key Takeaways
Catalan evidentiality is distributed across constructions. Use deure + infinitive for inference, semblar for appearance, es veu que for conversationally distanced information, segons for explicit sources, and the journalistic conditional for unconfirmed reporting. Track mood in subordinate clauses, scope in reordered sentences, commas around detached source frames, and clitics required by displaced arguments. Most importantly, distinguish uncertainty about a proposition from distance from its source: they are related, but not the same meaning.
