German Free Relative Clauses: Wer, Was & Case Clashes
Grammar Rule in 30 Seconds
Free relative clauses use 'wer' or 'was' to act as both the antecedent and the relative pronoun simultaneously.
- Use 'wer' for people: 'Wer das sagt, hat recht.' (Whoever says that is right.)
- Use 'was' for things or abstract concepts: 'Was du sagst, ist falsch.' (Whatever you say is wrong.)
- The case of the relative pronoun is determined by its role inside the relative clause.
Overview
German Free Relative Clauses (Freie Relativsätze), often introduced by wer (whoever) or was (whatever), represent a sophisticated grammatical structure characteristic of C2-level German. Unlike standard relative clauses that modify an existing noun (der Mann, der... – the man, who...), free relative clauses function as a noun phrase themselves. They do not refer back to a specific antecedent noun; instead, they substitute for one, acting as the subject or object of the main clause.
This structural autonomy allows for concise generalizations and the articulation of abstract concepts or indefinite entities.
Linguistically, a free relative clause can be understood as a nominalized clause, meaning an entire clause (Satz) takes on the role of a noun (Nomen). This transformation condenses meaning, enabling statements like Wer schweigt, stimmt zu. (Whoever is silent, agrees.) or Was zählt, ist die innere Einstellung. (What counts is the inner attitude.). Mastering these clauses is crucial for expressing complex thoughts with precision and for understanding nuanced German discourse, ranging from proverbs to academic writing.
How This Grammar Works
wer, wen, wem, was, or wo- compounds) simultaneously performs two distinct grammatical roles:- 1Internal Case: Within its own subordinate clause, the relative pronoun assumes a specific grammatical case (
Nominativ,Akkusativ,Dativ) determined by its role inside that clause. For example, inWer kommt, ...,weris the nominative subject ofkommt. - 2External Case: The entire free relative clause acts as a constituent (e.g., subject, direct object, indirect object, or object of a preposition) within the main sentence. Consequently, this whole clause requires a grammatical case determined by its function in the main sentence. For example, in
Wen ich liebe, den heirate ich., the entire clauseWen ich liebeis the direct object ofheirate ich.
der, die, das, dem, den) in the main clause.Wem nicht zu helfen ist, der ist nicht zu retten. Here, wem is dative within the free relative clause (Wem ist nicht zu helfen). However, the entire clause Wem nicht zu helfen ist acts as the nominative subject of the main clause, hence the resumptive pronoun der (nominative masculine singular, referring to the implied 'person'). Without der, the sentence would be grammatically incomplete and confusing.der Mann, der...) | Is the antecedent; no preceding noun |wer (persons), was (things/situations) |Formation Pattern
[Free Relative Clause], [Main Clause]. Remember that free relative clauses are subordinate clauses, meaning the finite verb within them moves to the end.
wer.
wer (Nominativ): Wer schweigt, der stimmt zu. (Whoever is silent, agrees.)
wen (Akkusativ): Wen ich liebe, den heirate ich. (Whomever I love, him I marry.)
wem (Dativ): Wem ich vertraue, dem erzähle ich alles. (To whomever I trust, to him I tell everything.)
wessen) is rare with wer in this specific free relative clause construction; it's typically rephrased or appears in other contexts. Instead of Wessen Buch ist das?, you might use Das Buch von dem, der es geschrieben hat. in a more complex scenario.
was.
was (Nominativ/Akkusativ): Was du heute kannst besorgen, das verschiebe nicht auf morgen. (What you can do today, do not postpone until tomorrow.)
was refers to a preceding entire sentence or situation, it functions similar to 'which' in English: Er hat gelogen, was mich sehr enttäuscht hat. (He lied, which disappointed me greatly.)
wo- compounds.
worauf (on what), worum (about what), womit (with what).
Worauf du wartest, das wird nie geschehen. (What you are waiting for, that will never happen.)
Womit er arbeitet, damit kenne ich mich nicht aus. (What he works with, with that I am not familiar.)
Wen du gestern getroffen hast, ... (Whom you met yesterday, ...)
der, die, das, dem, den) in the main clause serves to make the external case of the free relative clause explicit. It typically refers back to the implied antecedent (masculine singular for wer, neuter singular for was).
Wem nicht zu helfen ist, der ist nicht zu retten.
Wer Fehler macht, den bestraft das Leben.
Wer will, (der) kann. (Whoever wants to, can.)
Was ich habe, (das) gebe ich dir. (What I have, I give to you.)

When To Use It
- 1Generalizations, Proverbs, and Maxims: This is perhaps their most common and iconic use. They allow you to make broad statements that apply to any person or situation fitting the description.
Wer nicht wagt, der nicht gewinnt.(Whoever doesn't dare, doesn't win.)Was man nicht weiß, das macht einen nicht heiß.(What one doesn't know, doesn't bother one.)
- 1Referring to Undefined or Indefinite Entities: When the specific person or thing is unknown, irrelevant, or intentionally left unspecified, free relative clauses are ideal. They replace phrases like
derjenige, der...(the one who...).
Ich gebe, wem ich will.(I give to whomever I want.) –wemrefers to an unspecified person.Nimm, was du brauchst.(Take what you need.) –wasrefers to an indefinite quantity or type of things.
- 1Referring to Entire Situations or Preceding Clauses (with
was): The pronounwascan concisely summarize a preceding action, statement, or entire scenario, similar to 'which' referring to a whole clause in English. This is particularly common in both formal and informal speech.
Er hat das Rennen gewonnen, was niemand erwartet hatte.(He won the race, which no one had expected.) –wasrefers to the entire event of winning the race.Sie hat nicht geantwortet, was mich beunruhigt.(She didn't answer, which worries me.)
- 1Emphasis and Clarity: By isolating the relative clause at the beginning of the sentence and using a resumptive pronoun, you draw attention to the conditional or general statement being made. This structure can add a certain gravitas or analytical precision to your language, reflecting a characteristic of German linguistic style that values explicit structural signaling.
- 1Fixed Expressions and Formal Language: Many idiomatic expressions and more formal or literary texts utilize free relative clauses. Recognizing these patterns enhances comprehension of sophisticated German.
Was du nicht willst, das man dir tu', das füg' auch keinem anderen zu.(What you don't want done to you, don't do to anyone else.)
Common Mistakes
- 1Omitting the Resumptive Pronoun (
der,dem,den,das) in Case Clashes: This is arguably the most frequent and significant error. When the internal case of the relative pronoun (wer,wen,wem,was) differs from the external case required by the main clause, the resumptive pronoun is mandatory for grammatical integrity. Its absence leads to grammatically incomplete sentences that confuse native speakers.
- Incorrect:
Wem das Buch gefällt, kann es behalten.(Grammatically ambiguous;Wemis Dative, but the main clause needs a Nominative subject.) - Correct:
Wem das Buch gefällt, der kann es behalten.(derprovides the Nominative subject forkann es behalten.) - Incorrect:
Was du hast, gib mir.(Missing explicit object forgib mir.) - Correct:
Was du hast, das gib mir.(dasfunctions as the Accusative direct object ofgib mir.)
- 1Confusing
werandwas: Learners sometimes usewasto refer to people, which is grammatically incorrect and considered highly impolite in German.Wer(and its formswen,wem) is exclusively for persons, whilewasis for things, concepts, or situations.
- Incorrect:
Was das gesagt hat, muss verrückt sein. - Correct:
Wer das gesagt hat, der muss verrückt sein.
- 1Incorrect Case of the Resumptive Pronoun: The resumptive pronoun must match the external case required by the main clause, not the internal case of the relative pronoun. It also generally refers to a masculine singular implied antecedent for
werand a neuter singular forwas.
- Incorrect:
Wem du hilfst, den gebe ich eine Belohnung.(denis Accusative, but the main clauseich gebe ... eine Belohnungneeds a Dative indirect object for the person being rewarded.) - Correct:
Wem du hilfst, dem gebe ich eine Belohnung.(demis Dative, matching the indirect object role in the main clause.)
- 1Confusing Free Relative Clauses with Indirect Questions: While structurally similar, their functions differ. An indirect question reports a question and usually follows verbs of knowing, asking, or wondering (
wissen,fragen,sich wundern). A free relative clause makes a statement about an unspecified entity.
- Indirect Question:
Ich weiß nicht, wer angerufen hat.(I don't know who called.) - Free Relative Clause:
Wer angerufen hat, der soll sich melden.(Whoever called, should report.)
- 1Incorrect Word Order: Forgetting that the free relative clause is a subordinate clause means the finite verb must be at the very end.
- Incorrect:
Was ich brauche ist das. - Correct:
Was ich brauche, das ist es.
- 1Overuse in Simpler Contexts: While elegant, using free relative clauses where a simpler noun phrase or a demonstrative pronoun would suffice can sound overly formal or contrived in casual speech. Judge the context carefully.
Real Conversations
Free relative clauses, particularly those with was, are surprisingly common in everyday German, demonstrating their versatility beyond formal contexts. Their conciseness makes them suitable for quick, impactful communication in various settings.
1. Texting and Social Media: In informal digital communication, the resumptive pronoun is sometimes omitted if the context is absolutely clear and the cases happen to align, or if speakers prioritize brevity, although this is generally an exception rather than the rule for C2-level correctness.
- Wer jetzt nicht lacht, versteht nix 😂 (Whoever doesn't laugh now, understands nothing.) – Implied: der versteht nix.
- Was du postest, bleibt im Netz. (What you post, stays online.) – Implied: das bleibt im Netz.
2. Casual Speech: You'll frequently hear was free relative clauses referring to situations or general statements. They contribute to a fluid conversational style.
- Ich esse einfach, was da ist. (I just eat what's there.)
- Was soll das? (What's that supposed to mean?) – A common idiomatic question, though Was soll das, das du da machst? would be a formal free relative variant.
- Was mich wirklich stört, ist die Unpünktlichkeit. (What really bothers me is the unpunctuality.)
3. Work Emails and Formal Discussions: Here, the full, grammatically correct structure with the resumptive pronoun is almost always maintained to ensure clarity and professionalism.
- Wer die Richtlinien nicht beachtet, den müssen wir leider ermahnen. (Whoever disregards the guidelines, him we unfortunately have to admonish.)
- Was im Meeting besprochen wurde, das werden wir im Protokoll festhalten. (What was discussed in the meeting, that we will record in the minutes.)
4. Proverbial and General Statements: As noted, many German proverbs and common sayings are structured as free relative clauses, making them sound authoritative and universally applicable. These are deeply embedded in the language.
- Wer rastet, der rostet. (He who rests, rusts.)
- Was lange währt, wird endlich gut. (What lasts a long time, finally turns out well.)
Understanding these clauses in diverse contexts provides insight into the German linguistic preference for structurally robust and semantically dense expressions, even in informal communication. They are not merely an academic construction but an integral part of how native speakers communicate precisely.
Quick FAQ
- Can
wo-compounds be used in free relative clauses? - Yes, absolutely. For things or concepts that require a prepositional relationship,
wo-compounds (worauf,worum,wobei,wovon,worüber, etc.) are the correct choice within the free relative clause. These follow the same case clash rules, typically requiringdasas the resumptive pronoun in the main clause. Example:Worum es geht, das ist die Wahrheit.(What it's about, that is the truth.)
- How formal are free relative clauses?
- Free relative clauses with
weroften carry a more formal, proverbial, or philosophical tone. They are common in maxims and generalized statements. Clauses withwasare much more flexible and appear frequently in both formal and informal speech, especially when referring to entire situations or indefinite things. The presence or absence of the resumptive pronoun can also subtly affect formality, with its omission often indicating greater informality (but only where grammatically permissible).
- When can I omit the resumptive pronoun (
der,dem,den,das)? - You can only omit the resumptive pronoun when the internal case of the free relative pronoun matches the external case required by the main clause and the sentence remains unambiguously clear. Even then, its retention is often preferred for emphasis or to maintain a more formal, robust structure. In general, for C2-level German, it is safer and more grammatically sound to always include the resumptive pronoun unless you are completely certain of its optionality in a specific context.
- Example where omission is possible:
Wer will, (der) kann.(Both are Nominative.)
- Can
werorwasrefer to plural entities? - Grammatically,
werandwasare singular, and the verb in both the free relative clause and the main clause will be singular. However, semantically,wercan certainly imply a group of people (e.g.,Wer das tut, der ist mutig.– This could apply to multiple brave individuals). If you explicitly need to refer to a plural group, you would typically rephrase usingdiejenigen, die...(those who...) or a similar construction, as free relative clauses are designed for singular, generic reference.
- Are there genitive forms like
wessenin free relative clauses? - While
wessenis the genitive form ofwer, its use in the free relative clause construction is uncommon and often avoided or rephrased. For instance, instead of directly sayingWessen Auto kaputt ist, ..., you would likely opt for a construction likeDas Auto von dem, der es kaputt gemacht hat, ...or a sentence implying possession without a direct genitive relative pronoun within this specific structure. Similarly forwas, genitive is not directly formed withwasin this way; one would use a prepositional phrase ordessen/derenreferring to an implieddas Ding.
- How do these relate to nominalized adjectives or participles?
- Free relative clauses share a conceptual similarity with nominalized adjectives or participles (
der Reisende– the traveler) in that they both convert a descriptive element into a noun. However, free relative clauses go a step further by nominalizing an entire clause, allowing for more complex, complete statements to function as a single noun phrase within a larger sentence. This reflects German's capacity for creating highly dense and information-rich grammatical units.
