Possessive Articles in German

In Brief

German uses mein, dein, sein, ihr, unser, euer, ihr and formal Ihr before nouns to express relationships and possession. Choose the stem from the owner, then choose the ending from the following noun's gender, number, and case (its role in the sentence): mein Bruder, meine Schwester, meinen Bruder. These words follow the same ending pattern as ein and kein.

Overview

Possessive articles are words placed before a noun (a word for a person, thing, place, or idea): mein Buch “my book,” deine Adresse “your address,” and unsere Freunde “our friends.” They are often called possessive determiners in English grammar. In German, they cover more than legal ownership: meine Mutter, for example, means “my mother,” not someone you own.

This is an A1 topic because these forms appear whenever you introduce family members, identify belongings, give contact details, or ask about another person's life. English-speaking learners need to make two choices where English normally makes only one. First, the owner determines the basic form: mein- for “my,” dein- for informal singular “your,” and so on. Then the noun determines the ending.

That second choice is the key. In seine Mutter “his mother,” sein- refers to a male owner, while -e appears because Mutter is feminine. In ihr Bruder “her brother,” ihr- refers to a female owner, but there is no ending because Bruder is masculine and nominative. Do not try to make the ending agree with the owner's sex.

How It Works

Step 1: choose the stem from the owner

Owner	Stem	Meaning	Example
ich	mein-	my	mein Name
du	dein-	your, informal singular	dein Name
er	sein-	his	sein Name
sie	ihr-	her	ihr Name
es	sein-	its	sein Name
wir	unser-	our	unser Name
ihr	euer-	your, informal plural	euer Name
sie	ihr-	their	ihr Name
Sie	Ihr-	your, formal	Ihr Name

The German owner words er, sie, and es refer to grammatical gender as well as people. Therefore, the appropriate possessive depends on the German noun used for the owner. For example, der Hund leads to sein Futter “his/its food,” while die Katze leads to ihr Futter “her/its food.”

Several forms look alike:

• sein- can mean “his” or “its.”
• ihr- can mean “her” or “their.”
• Ihr-, with a capital I, means formal “your.”

The sentence and situation usually remove the ambiguity. German also capitalizes Ihr- in all its formal-address forms: Ihr Pass, Ihre Adresse, Ihren Termin.

Step 2: choose the ending from the noun

German nouns have grammatical gender: masculine, feminine, or neuter. Plural nouns form a fourth group for article endings. A possessive article also changes with case. The nominative commonly marks the subject (who or what does the action, or is being described). The accusative commonly marks the direct object (who or what the action directly affects).

For the A1 core, learn this table first:

Noun type	Nominative	Accusative	Nominative example	Accusative example
Masculine singular	mein	meinen	Mein Bruder kommt.	Ich sehe meinen Bruder.
Feminine singular	meine	meine	Meine Schwester kommt.	Ich sehe meine Schwester.
Neuter singular	mein	mein	Mein Kind kommt.	Ich sehe mein Kind.
Plural	meine	meine	Meine Freunde kommen.	Ich sehe meine Freunde.

Only masculine singular visibly changes between these two cases: mein → meinen. The same endings attach to every possessive stem: deinen Vater, seinen Vater, ihren Vater, unseren Vater, euren Vater, Ihren Vater.

The link with ein and kein

Possessive articles belong to the ein-word family. Their endings match those of ein “a/an” and kein “no/not a”:

Pattern	Masculine nominative	Feminine nominative	Neuter nominative	Masculine accusative
ein/kein	ein Mann	eine Frau	ein Kind	einen Mann
possessive	mein Mann	meine Frau	mein Kind	meinen Mann

This gives you a useful shortcut: if you would say eine, use an -e form such as meine or deine. If you would say einen, use an -en form such as meinen or deinen.

The special shape of euer

The stem euer- loses its second e before most endings:

No ending	With an ending
euer Vater	eure Mutter
euer Kind	euren Vater
—	eurem Kind, eurer Mutter

So write eure, not euere, in the standard forms learners normally need. The pronunciation also follows the shorter spelling.

One possessive article for each noun

A possessive article normally replaces another central article. Say mein Buch, not das mein Buch or ein mein Buch. Adjectives may come between it and the noun: mein neues Buch. The adjective has its own ending, a later topic; the possessive remains in the article position.

English uses an apostrophe construction with names, as in “Anna's coat.” German often uses a name plus -s too: Annas Mantel. But with a possessive article, there is no apostrophe and no -s added: ihr Mantel “her coat.”

Examples in Context

German	English	Note
Das ist mein Buch.	This is my book.	Neuter nominative after sein
Wo ist deine Tasche?	Where is your bag?	Feminine nominative
Seine Mutter ist Ärztin.	His mother is a doctor.	Male owner; feminine noun
Ihr Bruder wohnt in Köln.	Her brother lives in Cologne.	Female owner; masculine noun
Wir verkaufen unser Auto.	We are selling our car.	Neuter accusative has no ending
Habt ihr eure Schlüssel?	Do you have your keys?	Informal plural owner; plural noun
Ich besuche morgen meinen Vater.	I am visiting my father tomorrow.	Masculine accusative -en
Sie sucht ihre Brille.	She is looking for her glasses.	Brille is grammatically singular
Die Kinder machen ihre Hausaufgaben.	The children are doing their homework.	ihre means “their” here
Ist das dein Platz?	Is that your seat?	Informal singular “your”
Frau Berger, hier ist Ihr Kaffee.	Ms Berger, here is your coffee.	Formal Ihr is capitalized
Können Sie bitte Ihren Namen buchstabieren?	Can you spell your name, please?	Formal masculine accusative
Der Hund frisst sein Futter.	The dog is eating its food.	Hund is masculine, so sein
Lena und Paul besuchen ihre Großeltern.	Lena and Paul are visiting their grandparents.	Plural owners; plural object

Notice that English “your” corresponds to three different German stems. Use dein- for one person addressed informally, euer- for several people addressed informally, and Ihr- for one or more people addressed formally.

Common Mistakes

Making the ending agree with the owner

• Wrong: sein Mutter for “his mother”
• Right: seine Mutter
• Why: sein- identifies the male owner, but the ending agrees with Mutter, a feminine noun. Feminine nominative requires -e.

Missing the masculine accusative ending

• Wrong: Ich sehe mein Bruder.
• Right: Ich sehe meinen Bruder.
• Why: Bruder is the direct object and is masculine singular. The accusative form ends in -en.

Using dein for every kind of “your”

• Wrong: Ist das dein Zimmer? when speaking informally to several friends
• Right: Ist das euer Zimmer?
• Why: dein- addresses one person informally; euer- addresses more than one. In formal address, use Ist das Ihr Zimmer?

Keeping both e's in euer before an ending

• Wrong: euere Wohnung, eueren Hund
• Right: eure Wohnung, euren Hund
• Why: Standard euer- normally drops its second e when an ending is attached.

Confusing her, their, and formal your

• Potentially wrong: Wo ist ihr Pass? when directly asking a customer
• Right: Wo ist Ihr Pass?
• Why: Lowercase ihr- means “her” or “their.” Capitalized Ihr- is the formal “your.” At the beginning of a sentence capitalization alone may not distinguish them, so context matters.

Adding another article

• Wrong: Das ist das mein Fahrrad.
• Right: Das ist mein Fahrrad.
• Why: The possessive already fills the article position. German does not normally combine it with der/die/das or ein/eine.

Usage Notes

Possession is interpreted from context

German often uses the same possessive construction for family, body parts, belongings, roles, and personal information: meine Tochter, meine Hand, mein Laptop, mein Chef, meine Adresse. It does not necessarily claim ownership. In a sentence such as Mein Zug fährt um acht, mein means “the train relevant to my journey.”

Formal and informal address

Use dein- with one person you address as du, and euer- with a group you address as ihr. Use Ihr- with any person or group you address as Sie. The same social choice must remain consistent across the sentence:

• Hast du deinen Ausweis? — informal, one person
• Habt ihr eure Ausweise? — informal, several people
• Haben Sie Ihren Ausweis? — formal

Whether people use du or Sie depends on relationship, setting, age, workplace culture, and region. When Sie is appropriate, its possessive is always capitalized.

German sometimes avoids a possessive with body parts

English strongly favors “my hand,” “your hair,” and similar phrases. German often uses a definite article when the person is already shown by a dative reflexive pronoun (a word referring back to the subject):

• Ich wasche mir die Hände. — “I wash my hands.”
• Sie putzt sich die Zähne. — “She brushes her teeth.”

Ich wasche meine Hände is grammatically possible, but it can sound more contrastive: my hands rather than something else. This pattern belongs beyond the first A1 rule, so do not let it stop you from using ordinary phrases such as Meine Hand tut weh “My hand hurts.”

Beyond the Basics / Advanced Use

You do not need to master the full case system at A1, but the possessive stems remain the same in later cases. Only the endings change. The complete singular-and-plural pattern below uses mein- as the model:

Case	Masculine	Feminine	Neuter	Plural
Nominative	mein Vater	meine Mutter	mein Kind	meine Freunde
Accusative	meinen Vater	meine Mutter	mein Kind	meine Freunde
Dative	meinem Vater	meiner Mutter	meinem Kind	meinen Freunden
Genitive	meines Vaters	meiner Mutter	meines Kindes	meiner Freunde

The dative often marks a recipient or follows certain prepositions: mit meinem Bruder “with my brother,” bei ihrer Freundin “at her friend's place.” Dative plural also commonly adds -n to the noun when possible: mit meinen Freunden.

The genitive can express belonging and appears more often in formal or written German: der Name meines Vaters “my father's name.” In everyday speech, other structures may compete with it, but these genitive endings are standard and useful to recognize.

A possessive article can also introduce an adjective. Because possessives behave like ein, the adjective sometimes carries information that the article does not visibly show:

• mein neuer Laptop — my new laptop
• meine neue Tasche — my new bag
• mit meinem neuen Laptop — with my new laptop

These adjective endings form their own system. First learn to choose the possessive article correctly; then add adjective declension.

Finally, distinguish a possessive article from a possessive pronoun. An article has a noun after it: Das ist mein Buch. A pronoun stands alone because the noun is understood: Das Buch ist meins “The book is mine,” or Ist das deiner? “Is that yours?” Stand-alone forms have a related but separate set of endings.

Practice Tips

1. Use a two-step check. For every phrase, ask: “Who is the owner?” to choose the stem, then “What noun follows, and what is its role?” to choose the ending. Say the reasoning aloud for examples such as ihren Bruder.
2. Build four-item noun sets. Take one stem and pair it with a masculine, feminine, neuter, and plural noun: dein Tisch, deine Lampe, dein Bett, deine Bücher. Then turn the masculine noun into an object: Ich kaufe deinen Tisch.
3. Practice all three versions of “your.” Rewrite a useful question for du, ihr, and Sie: Wie ist deine Adresse? Wie ist eure Adresse? Wie ist Ihre Adresse? This trains both endings and register.
