German Pronouns

In German, pronouns are called "Pronomen " or "Fürwörter". A Pronoun is used as a substitute for a noun or a noun phrase. German pronouns decline according to the specific person (1st person, 2nd person or 3rd person), numerous (singular or plural), and case (nominative, accusative, dative, genitive).

Pronouns are subdivided into:

  1. Personal pronouns (Personalpronomen)
  2. Possessive pronouns (Possessivpronomen)
  3. Demonstrative pronouns (Demonstrativpronomen)
  4. Reflexive pronouns (Reflexivpronomen)
  5. Relative pronouns (Relativpronomen)
  6. Indefinite pronouns (Indefinitpronomen)
  7. Interrogative pronouns (Interrogativpronomen)

1. German personal pronouns

Singular Plural
First person
ich (I) wir (we)
Second person, familiar form
du (you) ihr (you)
Second person, polite form
Sie (you) Sie (you)
Third person
er (he)
es (it)
sie (she)
sie (they)

Person Nominativ Akkusativ Dativ Genitiv
Singular 1. Person ich mich mir meiner
2. Person du dich dir deiner
Sie Sie Ihnen Ihrer
3. Person er ihn ihm seiner
sie sie ihr ihrer
es es ihm seiner
Plural 1. Person wir uns uns unser
2. Person ihr euch euch euer
3. Person sie sie ihnen ihrer

Plural of 2nd person polite form is same as singular. Use of personal pronouns in the genitive case very rare. They are only used with certain words or phrases that require genitive. Normally, they are replaced by dative personal pronouns.

2. German possessive pronouns

Possessive pronouns (Possessivpronomen) can serve two functions. Either they accompany the noun to show possession. (“This is my book.”) Or they replace a noun that was previously mentioned (“This is Jan's book. Mine is there.”). In the second example, the noun book was replaced by mine.

  1. German possessive words that accompany the noun to show possession are also called Possessive articles.
  2. German Possessive words that replace the noun to show possession are called Possessive pronouns.

Possessive articles and possessive pronouns are explained in detail after the following table.
German possessive pronouns are:

Singular Plural
First person
mein (my) unser (our)
Second person, familiar form
dein (your) euer (your)
Second person, polite form
Ihr (your) Ihr (your)
Third person
sein (his)
sein (its)
ihr (her)
ihr (their)

2.1 Possessive pronouns and possessive articles

There is a slight difference between possessive pronouns and possessive articles. In German, the declension of possessive pronouns and possessive articles is different.

Possessive article: When there's a noun after possessive word, it's a possessive article (Possessivartikel). In English, a more common name for possessive article (Possessivartikel) is possessive adjective. So, there's a slight naming convention's difference too. In English these are: 'my' 'your' 'his' 'her' 'its' 'our' and 'their'.
Wem gehört der Hund? (Who owns the dog?)
Das ist mein Hund. (This is my dog.)

Possessive pronoun: When there's no noun after possessive word, it's a possessive pronoun (Possessivpronomen). In English, possessive pronouns are mine, yours, his, hers, its, ours, yours, and theirs.
Wem gehört der Hund? (Who owns the dog?)
Das ist meiner. (This is mine.)
Sebastian nimmt Hans Motorrad, denn seins ist kaputt. (Sebastian takes Hans motorcycle because his is broken.)

2.2 Other naming conventions for possessive pronouns and possisseive articles in German

Possessive articles are also called 'Attributive possessive pronouns' (Attributive Possessivpronomen).
Possessive pronouns are also called:
'Substantive possessive pronouns' (Substantivische Possessivpronomen) or
'Adjective possessive pronouns' (Adjektiv Possessivpronomen).

The above table clearly shows that possessive pronouns always get the ending of the particular indefinite article.

Adding 's' or 'es' to neutral possessive pronouns in nominative and accusative

In spoken language, ending 's' is more common, while in written language 'es' is considered more formal. Both endings are correct.
Das ist meins. / Das ist meines. (This is mine.)
Das ist deins. / Das ist deines. (This is yours.)
Das ist ihrs. / Das ist ihres. (This is hers. / This is theirs.)
'unser' and 'euer' always take 'es' ending due to their pronunciations.
Das ist unseres. (This is ours.)
Das ist eures. (This is yours.)
Please pay attentions to spellings of 'eures'.

der, das, die, (that),
dieser (this), jener (that),
derjenige (the one, that one), derselbe (the same).

3.1 Demonstrative pronouns der, das, die

Demonstrative pronouns 'der', 'das' and 'die' are used to point out someone/something at a distance. Normally, they are translated as 'that' in English, but they can also represent 'this', if the distance to an object or person is small.
Das ist mein Auto. (That is my car.)

Derjenige and derselbe can be used as pronouns and aricles.

As an article:
Sie hat mir dasselbe Buch gezeigt. (She showed me the same book.)

As a pronoun:
Das gleiche Buch habe ich zu Hause. (I have the same book at home.)
Dasselbe habe ich schon zu Hause. (I already have the same at home.)

4. German reflexive pronouns

All reflexive pronouns (Reflexivpronomen) are in the objective case (accusative and dative) i.e. a reflexive pronoun act either as a direct object or an indirect object. Reflexive pronouns are never used in nominative case because they always refer to the subject. They have rare use in genitive.

Sie kennt sich sehr gut. (She knows herself very well.)
Du musst dich beeilen. Du bist schon zu spät. (You have to hurry up. You're already too late.)
Ich erinnere mich nicht. Kennen wir uns schon? (I do not remember. Do we know each other?)

This is short form of "ist alles klar bei dir/Ihnen?" and is used colloquially.

Alles läuft gut bis jetzt. (Everything is going well so far.)

6.6 man

The English indefinite pronoun 'one' can be translated as "man" in German. The pronoun "man" (one) should not be confused with the noun "Mann" (man).
"Man" is an impersonal indefinite pronoun. It is used for non-specific person/persons. Unlike the German noun "Mann", the pronoun "man" has general gender, i.e. it can replace masculine, feminine and neuter nouns, both in singular as well as in plural forms. However, the attached verb is always used in the 3rd person singular.

Man sollte hier langsam fahren. Es gibt viele Schulen auf dieser Straße. (One should drive slowly here. There are many schools on this street.)

Like the English pronoun 'one', "man" can also refer/represent all three grammatical persons. The above sentence "Man sollte hier langsam fahren", can also refer to 1st person,
Man sollte hier langsam fahren. (We should drive slowly here.)
Or if you don't want to address somebody directly,
Man sollte hier langsam fahren. (You should drive slowly here.)

The indefinite pronoun "man" is only used the nominative. In the accusative and dative cases, "man" changes into "einen" and "einem" respectively. It has no use in the genitive case.

Declension of indefinite pronoun "man"
Nominativ Akkusativ Dativ
man einen einem

Was soll man machen, wenn einen alles nervt? (What should you do if everything annoys you?)
Wenn man schlechte Gesundheit hat, kann einem es viele Probleme machen. (Having bad health can cause one a lot of problems. / If you have poor health, it can cause you many problems.)

The pronoun "man" is extensively used in everyday language, where the subject is not important or in daily life general statements. Like:
Man soll nie lügen. (One should never lie.)
Man soll immer pünktlich sein. (One should always be punctual.)
Man muss Geduld haben. / Man muss geduldig sein. (One has to be patient.)

If the main clause in a sentence is using "man" as a subject, the subordinate clause must also use "man" as a pronoun. The use of personal pronouns (er/es/sie) instead of the indefinite pronoun "man" in such sentences is wrong. For example, the following sentence is not correct.
Wenn man Klausur schreiben will, muss er gut vorbereiten. (If you want to write an exam, you have to prepare well.)
The correct pronoun in the dependent clause would also be "man".
Wenn man Klausur schreiben will, muss man gut vorbereiten.

6.7 jemand

"Jemand" (somebody, someone, anybody, anyone) is used to refer to a non-specific person. It is not gender-specific and can replace all three types of German nouns (masculine, feminine and neuter). "Jemand" can only be used in singular form and always uses conjugation form of third-person singular.

Spricht hier jemand Englisch? (Does anyone here speak English?)
Ist jemand da? (Is someone there?)
Die ganze Halle ist leer. Wann wird jemand kommen? (The whole hall is empty. When will someone come?)
Jemand muss ihm helfen. (Someone has to help him.)

In some cases, "jemand" can also be used in place of the indefinite pronoun "man", but only when "man" is used in the singular form. Please see the following examples to understand the difference in the use of "jemand" and "man" in the subordinate clauses.

Wenn man Klausur schreiben will, muss man gut vorbereiten.
Wenn jemand Klausur schreiben will, muss er gut vorbereiten.

A subordinate clause must use the pronoun "man" if the main clause is using "man" as a subject. In the case of "jemand" as a subject of the main clause, respective third-person singular pronoun (er/es/sie) will be used in the subordinate clause.

"Jemand" can be combined with the suffix "irgend-" to form "irgendjemand". "Irgendjemand" shows more indefiniteness than just "jemand".

"Jemand" is inflected like articles, but normally it is used in un-inflected form, especially in spoken German. Both ways are correct.

7.6 welch-

"Welch-" (which) can be used to ask questions about person/persons and thing/things. It refers to a smaller number/numbers out of a bigger number/quantity. We have already seen the declension of "welch-" as a relative pronoun and its plural declined forms as an indefinite pronoun.

The declension of "welch-" as an interrogative pronoun is the same as an indefinite pronoun or as a relative pronoun. However, we have no genitive form of "welch-" in relative pronoun's declension and no singular forms in indefinite pronoun's declension.

As an interrogative pronoun, "welch-" can have genitive forms. Below is the complete declension table of "welch-".
