Relative-Clause Errors | Catalan Grammar

Relative-clause errors are rarely random. English encourages a learner to leave a preposition at the end and to put “whose” before a noun; contact with Spanish can suggest cuyo or reinforce an all-purpose que; spontaneous Catalan itself often uses a resumptive clitic. A useful correction therefore asks which role the antecedent has inside the relative clause and which register the sentence belongs to before replacing anything.

This page is a repair manual, not a second presentation of every relative pronoun. The full paradigms appear under prepositional relatives, possessive relatives, and relative que.

A repeatable diagnosis

Temporarily turn the relative into an independent clause and restore the antecedent. That exposes the missing function.

Underlying clause	Function recovered	Standard relative
Treballo amb la Núria	amb person	la Núria amb qui treballo
Parlem del conveni	de thing	el conveni de què parlem
El pressupost de l'entitat ha crescut	possessor inside a noun phrase	l'entitat el pressupost de la qual ha crescut
Tots els ponents van arribar tard	nonrestrictive comment	els ponents, que van arribar tard, ...

Then use four checks: preserve the required preposition; select a relative that can carry that function; delete any clitic or strong pronoun that repeats it; and decide whether the relative identifies a subset or merely comments on an already identified referent.

💡

If you cannot say what the gap stands for in the reconstructed clause, do not choose the relative by translating an English word. Reconstruct first: en aquesta oficina becomes l'oficina en què; els socis de l'empresa becomes l'empresa els socis de la qual.

Common Mistakes

Ten repairs, with the reason for each

1. Do not strand a preposition

❌ La consultora que treballem amb presentarà l'informe dilluns.

Incorrect in standard Catalan: this strands amb at the end in imitation of English.

✅ La consultora amb qui treballem presentarà l'informe dilluns.

The consultant we work with will present the report on Monday.

The test is treballem amb la consultora. Because the antecedent is a person, the complete phrase becomes amb qui. Catalan does not copy English “the consultant we work with.”

❌ Aquest és el protocol que totes les decisions depenen de.

Incorrect in standard Catalan: de has been left without its complement.

✅ Aquest és el protocol de què depenen totes les decisions.

This is the protocol on which all the decisions depend.

The verb phrase is dependre del protocol. For a nonhuman antecedent after simple de, use stressed què. The accent distinguishes this relative from unstressed que.

2. Rebuild English “whose” rather than calquing it

❌ Hem visitat una cooperativa que els seus productes s'exporten arreu.

Not appropriate in edited formal Catalan: que plus a possessive calques an analytic spoken pattern.

✅ Hem visitat una cooperativa els productes de la qual s'exporten arreu.

We visited a cooperative whose products are exported everywhere.

Start from els productes de la cooperativa. The possessed noun comes first, and de la qual agrees with feminine singular cooperativa, not with plural productes. The rejected version is widespread in informal speech, so it should be edited for register rather than condemned as nonexistent Catalan.

❌ És un compositor cuyo nom encara no consta al programa.

Incorrect: cuyo is a Spanish relative determiner, not a Catalan form.

✅ És un compositor el nom del qual encara no consta al programa.

He is a composer whose name is not yet listed in the programme.

The false analogy comes directly from Spanish cuyo. Contemporary Catalan uses el nom del qual in formal prose or recasts the sentence in conversation: És un compositor que encara no surt al programa.

❌ Conec dues enginyeres els projectes del qual han rebut finançament europeu.

Incorrect: del qual wrongly agrees with projectes instead of the antecedent.

✅ Conec dues enginyeres els projectes de les quals han rebut finançament europeu.

I know two engineers whose projects have received European funding.

The agreement test asks “whose?” The owners are dues enginyeres, feminine plural, hence de les quals. The possessed noun projectes controls its own article but not the form of qual.

3. Do not fill one gap twice in formal prose

❌ És una qüestió de què ja n'hem parlat diverses vegades.

Incorrect in the intended formal structure: de què and en represent the same complement.

✅ És una qüestió de què ja hem parlat diverses vegades.

It is an issue that we have already discussed several times.

Compare the independent clause ja n'hem parlat: there en replaces de la qüestió. Once de què occupies that slot, retaining en duplicates it. In informal, widespread Catalan, una qüestió que ja n'hem parlat is a real resumptive construction; the formal repair changes the whole pattern, not merely the accent.

❌ L'oficina en què hi treballava abans ha tancat.

Incorrect in edited standard Catalan: en què and hi both encode the workplace.

✅ L'oficina en què treballava abans ha tancat.

The office where I used to work has closed.

Restore treballava en aquella oficina. The fronted phrase en què already carries the locative complement, so hi has no unfilled role left.

❌ La metgessa amb qui vaig parlar amb ella em trucarà demà.

Incorrect: amb ella repeats the person already represented by amb qui.

✅ La metgessa amb qui vaig parlar em trucarà demà.

The doctor I spoke with will call me tomorrow.

English learners sometimes front a relative and still leave an overt pronoun behind. Catalan formal syntax permits one realization of this complement, not both. A clitic may remain only if it has a genuinely different referent or function.

4. Make the commas match the meaning

❌ La becària, que parla japonès prepararà la reunió amb Tòquio.

Incorrect punctuation: an opening comma for a nonrestrictive relative requires a closing comma.

✅ La becària, que parla japonès, prepararà la reunió amb Tòquio.

The intern, who speaks Japanese, will prepare the meeting with Tokyo.

Paired commas mark the relative as supplementary information. In speech, there is normally a pause before and after it. A single comma leaves the sentence's structure unresolved.

❌ Necessitem els arxius, que contenen la signatura digital.

Wrong for the intended meaning: the commas imply that all already identified files contain the signature.

✅ Necessitem els arxius que contenen la signatura digital.

We need the files that contain the digital signature.

Without commas, the clause selects which files are needed. With commas, it comments on a definite set of files already recoverable from context. The punctuation therefore changes reference; it is not a matter of breathing wherever a sentence feels long.

❌ La directora que ja coneixíeu, presentarà el nou pla.

Incorrect punctuation: a restrictive subject must not be separated from its verb by a lone comma.

✅ La directora que ja coneixíeu presentarà el nou pla.

The director you already knew will present the new plan.

Here que ja coneixíeu identifies which director. No comma belongs between the complete subject and presentarà. If the director were already unique, both commas would be possible: La directora, que ja coneixíeu, presentarà...

Two forms that are grammatical—but mean something else

The most dangerous “errors” are well-formed sentences that answer a different question.

Els tècnics que havien revisat la instal·lació van signar l'acta.

The technicians who had inspected the installation signed the report: only that subset signed it.

Els tècnics, que havien revisat la instal·lació, van signar l'acta.

The technicians, who had inspected the installation, signed the report: all the technicians in question had inspected it.

Neither sentence is defective. The first identifies a subset; the second presents the inspection as background about an already identified group. Replacing one with the other can change who signed.

Aquesta és la casa on parla la periodista cada vespre.

This is the house where the journalist speaks every evening.

Aquesta és la casa de què parla la periodista cada vespre.

This is the house that the journalist talks about every evening.

On is grammatical in the first sentence, but it fills a locative role: the speaking happens in the house. If the house is the topic of parlar de, the required relative is de què. The test is whether the reconstructed clause is parla a la casa or parla de la casa.

Regional usage and contact

The prepositional and possessive solutions taught here are accepted across the IEC and AVL standards. Central Catalan is the baseline of the examples, but the repair principles also apply in Valencian, Balearic, Northwestern, Northern, and Alguerese edited prose. Those varieties may differ in clitic forms and in how frequent resumptive relatives are in conversation; that does not turn a coherent regional system into an error.

Keep three diagnoses separate. English-driven stranding produces forms such as la persona que treballo amb. Spanish contact can introduce cuyo or favor structures modeled closely on Spanish. Native informal Catalan often uses que plus en, hi, a possessive, or a strong pronoun. A formal editor may recast that last pattern, but should label the register accurately rather than treating speakers' conversational grammar as failed formal Catalan. See colloquial resumptives for that distinction.

💡

A correction is complete only when it names the false analogy and provides a test: reconstruct the complement, choose the relative, remove duplication, and read the commas for reference.

Final proofreading checklist

Reconstruct the relative as an independent clause. Did you preserve the verb's preposition?
After a preposition, did you use què mainly for things, qui mainly for people, or an agreeing form of el qual where appropriate?
For possession, does del qual / de la qual / dels quals / de les quals agree with the antecedent rather than the possessed noun?
Does a fronted relative duplicate en, hi, a strong pronoun, or a possessive? If so, is that deliberate informal resumption or an error in edited prose?
Do two commas enclose a supplementary relative? Does the no-comma version select a subset?
Could on be changing “the place being discussed” into “the place where the action occurs”?
Have you mistaken a coherent Valencian, Balearic, Northwestern, Northern, or Alguerese form for an error?
Finally, read the repaired sentence aloud. The intended antecedent and the relative's role should be recoverable without backtracking.

Key Takeaways

Recover the missing role before editing: a stranded preposition, a possessor, a duplicated complement, and a restrictive comma problem need different repairs. Standard formal Catalan fronts the required preposition, builds possession with an agreeing form of del qual, and normally expresses a relative's complement only once. Commas distinguish identifying information from supplementary comment, so they can change reference rather than merely indicate a pause. Finally, separate English transfer and Spanish contact from coherent regional or informal Catalan before calling a form defective.
