Asking 'Who?' (wer, wen, wem, wessen)
Grammar Rule in 30 Seconds
Use 'wer' for subjects, 'wen' for direct objects, 'wem' for indirect objects, and 'wessen' for possession.
- Wer (Nominative): Who is doing the action? 'Wer kommt?'
- Wen (Accusative): Who is receiving the action? 'Wen siehst du?'
- Wem (Dative): To whom is something given? 'Wem hilfst du?'
Overview
The interrogative pronoun wer is fundamental for asking about persons in German. Unlike English, where 'who' often suffices across grammatical roles, German demands precision. The form of wer changes based on the grammatical case (Nominative, Accusative, Dative, Genitive) that the person being asked about occupies within the sentence.
This declension reflects the core principle of German grammar, where nouns and pronouns are inflected to indicate their function.
At the A2 level, understanding this declension is crucial for forming correct questions and comprehending responses. Think of wer as the human-specific counterpart to was (what), which is used for objects or concepts. While was remains constant, wer adapts, much like the definite article der (the) changes to den, dem, or des depending on its case.
This parallel is highly beneficial: the declension pattern of wer closely mirrors that of the masculine singular definite article.
This grammatical structure ensures that the grammatical role of the unknown person is unambiguous. For instance, asking Wer hat das Buch? (Who has the book?) clearly identifies the person as the subject performing the action, whereas Wen siehst du? (Whom do you see?) unequivocally marks the person as the direct object. Mastering these distinctions is a cornerstone of accurate German communication.
How This Grammar Works
wer, you must first ascertain the grammatical role of the person you are inquiring about. This requires a brief internal analysis of the sentence's structure and the verb's requirements. The four cases dictate which form of wer is appropriate:werwer.Werkommt heute Abend? (Who is coming tonight? –Weris the subject ofkommt.)Werhat den Kuchen gebacken? (Who baked the cake? –Weris the subject ofhat gebacken.)Werist der Lehrer? (Who is the teacher? –Weris the subject complement, referring to the subject.)
wenwen is used after certain accusative prepositions such as durch, für, gegen, ohne, um.Wensuchst du? (Whom/Who are you looking for? –Wenis the direct object ofsuchst.)Für wenist das Geschenk? (For whom is the gift? –Wenis the object of the prepositionfür.)Wenhat die Polizei verhaftet? (Whom did the police arrest? –Wenis the direct object ofhat verhaftet.)
wemhelfen (to help), geben (to give), gehören (to belong to), antworten (to answer)) and dative prepositions (e.g., aus, außer, bei, mit, nach, seit, von, zu).Wemgibst du die Blumen? (To whom are you giving the flowers? –Wemis the indirect object ofgibst.)Mit wemsprichst du? (With whom are you speaking? –Wemis the object of the prepositionmit.)Wemgehört das Buch? (To whom does the book belong? –Wemis the object of the dative verbgehört.)
wessenwessen directly precedes the noun it refers to.Wessender Laptop ist das? (Whose laptop is that? –Wessenindicates possession ofder Laptop.)WessenIdee war das? (Whose idea was that? –Wessenindicates possession ofdie Idee.)WessenFahrrad steht hier? (Whose bicycle is standing here? –Wessenindicates possession ofdas Fahrrad.)
wer can obscure the intended meaning, even if a native speaker might still infer your intent.Formation Pattern
wer is highly regular and mirrors the masculine singular definite article in Nominative, Accusative, and Dative, making it easier to learn if you are already familiar with article declension. The Genitive form, wessen, is unique but consistently applied.
wer:
wer | der | Subject of the sentence (who is doing the action?) |
wen | den | Direct object (who/whom is receiving the action?) |
wem | dem | Indirect object (to whom/for whom is the action?) or object of dative preposition/verb |
wessen | des | Possession (whose?) |
Wer is always grammatically singular, even when the answer might be plural (e.g., Wer kommt? - The children are coming). You do not need plural forms for wer.
wer (or wen, wem, wessen) always occupies Position 1 in the sentence. The conjugated verb immediately follows in Position 2.
Wer fährt das Auto? (Who drives the car?)
Wen liebst du? (Whom do you love?)
Wem hilft er? (Whom does he help?)
Wessen das Buch liest du? (Whose book are you reading?)
wessen, the noun describing the possessed item always follows wessen directly, similar to English 'whose + noun'. Wessen cannot stand alone in this construction.
When To Use It
wer, wen, wem, and wessen is essential for precise communication and is applicable across a vast array of everyday scenarios. It allows you to inquire specifically about the role a person plays in an action or relationship, moving beyond vague questions to grammatically accurate ones.wer):wer when you need to know who is performing an action or is the topic of the sentence. This is arguably the most frequent use case.- Identity:
Werist der neue Kollege? (Who is the new colleague?) - Action:
Werhat die Tür geöffnet? (Who opened the door?) - Responsibility:
Werist für das Projekt verantwortlich? (Who is responsible for the project?)
wen):wen when the person is directly affected by the verb, or after an accusative preposition. This form is critical for transitive verbs.- Observation:
Wenhast du im Supermarkt getroffen? (Whom did you meet in the supermarket?) - Selection:
Wenmöchten Sie einladen? (Whom would you like to invite?) - Purpose:
Für wenist diese Nachricht? (For whom is this message?)
wem):wem when the person is the recipient of an action, or when the verb or preposition demands the dative case. This usage clarifies the beneficiary or target of an action.- Recipient:
Wemhast du den Brief geschrieben? (To whom did you write the letter?) - Assistance:
Wemkannst du helfen? (Whom can you help? –helfentakes Dative) - Association:
Mit wemgehst du ins Kino? (With whom are you going to the cinema? –mittakes Dative)
wessen):wessen to determine ownership of an item. This directly substitutes for 'whose' in English, always preceding the noun it modifies.- Ownership:
Wessender Schlüssel ist das? (Whose key is that?) - Source:
WessenIdee war das eigentlich? (Whose idea was that, actually?) - Property:
WessenHandy klingelt? (Whose phone is ringing?)
Common Mistakes
wer, wen, wem, and wessen. These errors often stem from the simpler English pronoun system, which does not distinguish grammatical case with the same rigor as German.wer (The "Who"-only Error):wer for all cases, mimicking the English tendency to use 'who' even when 'whom' is grammatically correct. German, however, requires case distinction.- Incorrect:
Wersiehst du? (Literally: Who sees you? – implyingweris the subject. The verbsiehst(you see) already hasduas its subject, thuswermust be the object.) - Correct:
Wensiehst du? (Whom do you see?)
- Incorrect:
Werhilfst du? (Literally: Who helps you? –helfentakes Dative.) - Correct:
Wemhilfst du? (Whom do you help?)
wen or wem usage.- Prepositions: Remember that prepositions like
mit,nach,von,zualways take the Dative. Therefore, it's alwaysMit wem...?,Nach wem...?,Von wem...?,Zu wem...?. - Incorrect:
Mit wergehst du? (weris Nominative) - Correct:
Mit wemgehst du? (wemis Dative) - Verbs: Verbs such as
folgen(to follow),gratulieren(to congratulate),passen(to fit),schmecken(to taste good to) require a Dative object. If you're asking about the recipient of these actions,wemis necessary. - Incorrect:
Wenpasst das Hemd? (passentakes Dative) - Correct:
Wempasst das Hemd? (Whom does the shirt fit?)
wer with was:Wer is exclusively for persons. Was is for things, concepts, or actions. Using wer for non-human entities is grammatically incorrect, though colloquially acceptable for personified pets.- Incorrect:
Werist das auf dem Tisch? (Referring to an object) - Correct:
Wasist das auf dem Tisch? (What is that on the table?)
wessen:Wessen specifically denotes possession. Avoid combining it with prepositions like von (of/from), as wessen inherently carries that meaning.- Incorrect:
Von wessendas Buch ist das? (Redundant) - Correct:
Wessendas Buch ist das? (Whose book is that?)

Swiss German speakers often simplify case usage in casual settings, but standard German remains the norm for writing.
These pronouns derive from Proto-Germanic interrogative stems.
