Two-Way Prepositions: Motion vs. Location (in, auf, an)
Grammar Rule in 30 Seconds
Use Accusative for movement toward a destination and Dative for a static location.
- Movement (Wohin?): Use Accusative. Example: Ich gehe in {das|n} Kino.
- Location (Wo?): Use Dative. Example: Ich bin in {dem|n} Kino.
- The Big Three: in, auf, an are the most common two-way prepositions.
Overview
German two-way prepositions, known as Wechselpräpositionen (Wechselpräpositionen two-way prepositions), are pivotal for expressing spatial relationships. Unlike English, which often uses distinct prepositions (e.g., "in" vs. "into") to convey direction, German employs the same preposition and signals the difference through the grammatical case of the following noun.
This system allows for precise communication of both static location (Wo? – Where?) and dynamic motion (Wohin? – Where to?), a core principle reflecting German's grammatical emphasis on directionality.
These nine prepositions (an, auf, hinter, in, neben, über, unter, vor, zwischen) can govern either the Accusative or the Dative case. Your choice depends entirely on whether the sentence describes movement towards a destination or a fixed state at a location. Mastering this distinction is fundamental for A2 learners, enabling more accurate and nuanced expression in German, and revealing a deeper structural logic of the language.
How This Grammar Works
- Accusative Case for Motion / Direction (
Wohin?): When an action implies movement to, into, or onto a place, you must use the Accusative case. This answers the questionWohin?(Wohin? Where to?). Think of an arrow in flight, indicating a change of location from point A to point B. The action is dynamic, causing a shift in position or entry into a space. - Example (Movement
into):Ich gehe in das Kino.(I am going into the cinema.) The verbgehen(gehen to go) clearly indicates movement towards and into a destination, henceintakes Accusativedas(das the). - Example (Movement
onto):Er stellt die Tasse auf den Tisch.(He places the cup onto the table.) The verbstellen(stellen to place upright) describes an action of moving an object to a new upright position, requiringaufwith Accusativeden(der the). - Example (Movement
toa vertical surface):Sie hängt das Bild an die Wand.(She hangs the picture onto the wall.)hängen(hängen to hang something) here is dynamic, soangoverns Accusativedie(die the).
- Dative Case for Location / State (
Wo?): When a sentence describes something that is already situated at, in, or on a particular place, you must use the Dative case. This answers the questionWo?(Wo? Where at?). Visualize a pinned location on a map, representing a static, unchanging position. The state is static, with no inherent change of place, merely existing at a location. - Example (Location
in):Ich bin in dem Kino.(I am in the cinema.) The verbsein(sein to be) denotes a static state of being within the cinema, thusintakes Dativedem(das the). - Example (Location
on):Die Tasse steht auf dem Tisch.(The cup is on the table.) The verbstehen(stehen to stand/be standing) describes the static position of the cup, soaufgoverns Dativedem(der the). - Example (Location
ona vertical surface):Das Bild hängt an der Wand.(The picture hangs on the wall.) Here,hängen(hängen to be hanging) is static, leading toanwith Dativeder(die the).
Formation Pattern
der | Feminine die | Neuter das | Plural die |
den | die | das | die |
dem | der | dem | den (+-n on noun) |
die and neuter das nouns, the definite article in the Accusative case is identical to its Nominative form. Only masculine der nouns change (der → den). This makes masculine nouns particularly prominent in Accusative contexts.
der. This can be confusing, as der is also the masculine Nominative article; however, the presence of a Dative-governing preposition like in clearly establishes its Dative feminine function. For plural nouns in the Dative, the article is den, and an additional -n is typically appended to the plural noun itself, unless it already ends in -n or -s (e.g., in den Häusern (das Haus house), but mit den Autos (das Auto car)).
ein | Feminine eine | Neuter ein |
einen | eine | ein |
einem | einer | einem |
das (Accusative) and singular masculine/neuter dem or singular feminine der (Dative), reflecting a linguistic tendency towards efficiency in common phrases.
ins Kino - Acc.) | Example (im Restaurant - Dat.) |
in + das | ins (Accusative) | Ich gehe ins Kino. | – |
in + dem | im (Dative) | – | Ich bin im Restaurant. |
an + das | ans (Accusative) | Wir fahren ans Meer. | – |
an + dem | am (Dative) | – | Wir wohnen am Fluss. |
auf + das | aufs (Accusative) | Er springt aufs Dach. | – |
vors (vor + das) and hinters (hinter + das) exist but are encountered less frequently at the A2 level. It is crucial to remember that these contractions almost exclusively occur with singular articles and are rare or non-existent with plural forms.
When To Use It
Wohin?) or static (location, Wo?). This section details common scenarios and specific nuances for in, auf, and an, which are among the most frequently used.Wohin? vs. Wo?):Wohin?) | State (Dative - Wo?) | Meaning | Example Accusative (legen, stellen) | Example Dative (liegen, stehen) |legen (legen to lay something) | liegen (liegen to be lying) | Horizontal position | Ich lege das Buch auf den Tisch. | Das Buch liegt auf dem Tisch. |stellen (stellen to place upright) | stehen (stehen to be standing) | Vertical position | Wir stellen die Flasche in den Kühlschrank. | Die Flasche steht in dem Kühlschrank. |setzen (setzen to set/seat someone) | sitzen (sitzen to be sitting) | Seated position | Sie setzt das Kind auf den Stuhl. | Das Kind sitzt auf dem Stuhl. |hängen (hängen to hang something) | hängen (hängen to be hanging) | Suspended position | Er hängt das Bild an die Wand. | Das Bild hängt an der Wand. |stecken (stecken to stick/put in) | stecken (stecken to be stuck/located) | Inserted position | Ich stecke den Schlüssel in die Tasche. | Der Schlüssel steckt in der Tasche. |hängen and stecken are unique as they have the same verb form for both dynamic (transitive) and static (intransitive) meanings. In these instances, the case of the article is your only grammatical indicator of motion or location, making precise article declension even more critical.- Motion Verbs (Accusative):
gehen(gehen to go),fahren(fahren to drive/travel),fliegen(fliegen to fly),springen(springen to jump),laufen(laufen to run/walk),kommen(kommen to come). These verbs necessitate Accusative with a two-way preposition because they indicate movement towards something, implicitly crossing a boundary or arriving at a destination. Ich fahre in die Stadt.(I drive into the city.)Sie springt in das Wasser.(She jumps into the water.)Wir kommen an den Bahnhof.(We are coming to the train station.)
- Location Verbs (Dative):
sein(sein to be),bleiben(bleiben to stay),wohnen(wohnen to live),leben(leben to live),sich befinden(sich befinden to be located). These verbs describe a fixed state or existence, requiring Dative with a two-way preposition. Wir sind an dem Strand.(We are at the beach.)Er bleibt in dem Hotel.(He stays in the hotel.)Das Denkmal befindet sich auf dem Platz.(The monument is located on the square.)
in, auf, an:in(in in, into): Used for enclosed spaces, countries without articles, and cities. It implies being inside something or entering an interior space, often with clearly defined boundaries.- Motion (Accusative):
Wir gehen in das Museum.(We go into the museum.) This indicates entering an enclosed building. - Location (Dative):
Sie arbeiten in einem Büro.(They work in an office.) This describes being within an enclosed workspace. - Countries/Cities without articles: For cities (
Berlin) and most countries (Deutschland) without an article,nachis used for motion, andinfor location:Ich fahre nach Berlin./Ich bin in Berlin.For countries with articles (e.g.,die Schweiz(die Schweiz Switzerland),die USA(die USA USA)),infunctions as a two-way preposition:Ich fliege in die USA.(Acc.) /Ich lebe in den USA.(Dat.).
auf(auf on, onto): Primarily for horizontal surfaces, public places, islands, and events. It implies being on top of something or moving onto a surface. It can also refer to abstract concepts like

Cultural Notes

Austrians often use 'auf' more frequently for events.
Swiss German often simplifies these cases in spoken dialect.
These prepositions evolved from Old High German spatial markers.

Yes, when used spatially.
Use the question test: 'Wohin?' vs 'Wo?'.
Start with 'in', 'auf', and 'an'.
Because it requires thinking about case and verb type simultaneously.
