German articles change depending on the role a noun plays in the sentence. For masculine nouns, the indefinite article can be ein, einen or einem. This lesson shows you how to identify the subject, the direct object and the recipient, and how to use the correct form in useful sentences. You will also see that verbs and prepositions determine case, not just meaning. By the end, you will be able to talk about having, wanting, giving and helping with confidence.
By the end, you can…
- identify the subject, direct object and recipient in a simple German sentence.
- choose between ein, einen and einem for masculine nouns in the nominative, accusative and dative cases.
Listen once. Try it slowly. Then say it without looking.
Checking available voices…
Das ist ein Hund.
That is a dog.
dahs ist ayn hunt
Ein Hund is a predicate nominative after ist; Das is the subject. Both are nominative here. Do not identify every nominative noun as the subject.
Ich habe einen Hund.
I have a dog.
ikh HAH-buh EYE-nen hunt
Use einen for a masculine noun that is the direct object of haben (to have). This is the accusative case.
Ich gebe einem Freund ein Buch.
I give a friend a book.
ikh GAY-buh EYE-nem froynt ayn bookh
Use einem for a masculine recipient (indirect object). The verb geben (to give) takes the dative case for the person receiving something.
Kannst du einem Kind helfen?
Can you help a child?
kahnst doo EYE-nem kint HEL-fen
Use einem with the verb helfen (to help). Helfen takes the dative case, even though English uses a direct object.
Wir wohnen in einem Haus.
We live in a house.
veer VOH-nen in EYE-nem hows
Use einem after the preposition in when it means location (where?). This is the dative case. For direction (where to?), in takes the accusative: in ein Haus.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
The indefinite article for masculine nouns changes with case: nominative ein, accusative einen, dative einem. For feminine nouns, it is eine in both nominative and accusative, and einer in the dative. For neuter nouns, it is ein in both nominative and accusative, and einem in the dative. There is no plural form of ein. Positive indefinite plurals often have no article: Ich sehe Hunde. Keine Hunde is a negated plural, while die Hunde refers to definite dogs. Example: Das ist ein Mann (nominative). Ich sehe einen Mann (accusative). Ich helfe einem Mann (dative). For feminine: Das ist eine Frau. Ich sehe eine Frau. Ich helfe einer Frau. For neuter: Das ist ein Kind. Ich sehe ein Kind. Ich helfe einem Kind.
When to use it
The subject of a sentence is always in the nominative case. The direct object of most verbs is in the accusative case. The recipient or beneficiary of an action is often in the dative case. Some verbs, like helfen, danken, gefallen, gehören and antworten, always take the dative. Prepositions also determine case: in, an, auf, über, unter, vor, hinter, neben, zwischen take the accusative for direction (wohin?) and the dative for location (wo?). Other prepositions like mit, nach, aus, zu, von, bei, seit always take the dative. For example: Ich gehe in ein Haus (direction, accusative). Ich bin in einem Haus (location, dative). Ich komme mit einem Freund (dative after mit).
Listen to each line, then take one part and reply out loud.
Hast du einen Stift?
Do you have a pen?hahst doo EYE-nen shtiftJa, ich habe einen Stift. Brauchst du auch ein Blatt Papier?
Yes, I have a pen. Do you also need a piece of paper?yah, ikh HAH-buh EYE-nen shtift. BROWKHST doo owkh eye-n blaht pah-PEERJa, danke. Kannst du einem Freund auch einen Stift geben?
Yes, thanks. Can you also give a pen to a friend?yah, DAHN-kuh. KAHNST doo EYE-nem froynt owkh EYE-nen shtift GAY-benKlar, ich gebe einem Freund einen Stift.
Sure, I'll give a friend a pen.klahr, ikh GAY-buh EYE-nem froynt EYE-nen shtiftA little context goes a long way
In German, the dative case is also used after certain prepositions and verbs. It is not about politeness but about grammatical function. For example, helfen takes the dative, so you say Ich helfe einem Freund, not einen Freund. Similarly, the preposition mit always takes the dative: mit einem Freund. In southern Germany, Austria and Switzerland, some speakers use different forms in casual speech, but standard German uses the forms taught here.
One thing to watch for
Using einen after the verb helfen, as in Ich helfe einen Freund.
Try this instead: Helfen takes the dative case, so the correct form is Ich helfe einem Freund. The person you help is the dative recipient, not the accusative direct object.
Your turn
Try answering out loud before checking a possible answer.
1Complete the sentence: Ich sehe ___ Mann. (I see a man.)
Show a sample answer
einen
Mann is masculine and the direct object of sehen, so it takes the accusative case: einen. The nominative ein would be wrong here because the man is not the subject.
2Complete the sentence: Das ist ___ Frau. (That is a woman.)
Show a sample answer
eine
After sein, the noun phrase identifying the subject is in the nominative: Das ist ein Hund. Das is the subject and ein Hund is the predicate nominative. In Ich sehe einen Hund, the dog is the accusative object.
3Complete the sentence: Ich danke ___ Freund. (I thank a friend.)
Show a sample answer
einem
Danken takes the dative case, so the masculine noun Freund becomes einem Freund. The accusative einen would be incorrect because danken does not take a direct object.
For masculine nouns, use ein for the subject, einen for the direct object, and einem for the recipient or after dative verbs and prepositions. Always check the verb and the role of the noun in the sentence.
