am / um / vum / mam / beim
Preposition and Article Contractions
An dem becomes am, op dem becomes um, mat dem becomes mam: Ech sinn am Gaart. Ech fuere mam Bus.
How It Works
The contractions
- am = an dem: am Gaart, am Kino
- um = op dem (also un dem): um Dësch
- vum = vun dem: vum Supermarché
- mam = mat dem: mam Bus
- beim = bei dem: beim Dokter
- zum = zu dem: zum Beispill
- nom = no dem: nom Iessen
- virum = virun dem: virum Haus
In everyday language the short form is the normal one: beim Dokter sounds much more natural than bei dem Dokter.
Mostly with dem
Feminine nouns keep der: an der Stad, mat der Bomi. The one exception is zur (zu der): Meng Frëndin gehéiert scho bal zur Famill. Plurals keep den (de): mat de Kanner. See dem/der/den (dative).
Only in the dative
With movement, two-way prepositions take the accusative, and nothing merges: Ech ginn an de Kino, but Ech sinn am Kino. See two-way prepositions.
Not when pointing
If you mean that one, use the stressed form deem, which never merges: mat deem Mann do. See deen/déi/dat (demonstrative).
Um with clock times
In um aacht Auer, um is a separate word meaning at, not op dem. See time prepositions.
Examples (6)
- Ech sinn am Gaart.
I am in the garden.
Word by Word: I am in-the garden.
Gaart is masculine, and sinn describes a location, so an dem becomes am.
- D'Fläsch steet um Dësch.
The bottle is on the table.
Word by Word: The bottle stands on-the table.
Op dem becomes um.
- Ech fuere mam Bus op d'Aarbecht.
I go to work by bus.
Word by Word: I drive with-the bus to the work.
Mat dem becomes mam. Fueren becomes fuere before the m.
- Ech si muer beim Dokter.
I am at the doctor's tomorrow.
Word by Word: I am tomorrow at-the doctor.
Bei dem becomes beim.
- Si kënnt grad vum Supermarché.
She is just coming from the supermarket.
Word by Word: She comes just from-the supermarket.
Supermarché is masculine, so vun dem becomes vum.
- Nom Iessen drénke mer e Kaffi.
After the meal we will have a coffee.
Word by Word: After-the eating drink we a coffee.
Iessen is neuter, so no dem becomes nom.
Common Mistakes
Contracting with a feminine noun.
Ech sinn am Stad.Ech sinn an der Stad.Stad is feminine, so the dative article is der. Only dem merges with the preposition.
Using a dative contraction for movement toward a place.
Ech ginn am Kino.Ech ginn an de Kino.Going somewhere takes the accusative with an, so there is no dem to merge. Am Kino means in the cinema.
Contracting with a plural noun.
Ech spille mam Kanner.Ech spille mat de Kanner.Kanner is plural, and the plural dative article is den (de before K). It does not merge with mat.
