Introduce something or identify it
Im Flur steht ein Schrank. Der Schrank ist offen. first introduces a cupboard, then refers back to it. But “first mention = ein” is only a shortcut: Bitte schließ die Tür. can identify the room’s obvious door without any earlier mention. The listener’s shared context matters as much as the preceding sentence.
Ein does not necessarily mean that the speaker does not know which object it is. Ich habe einen Termin bei meiner Ärztin. can describe a particular appointment that is new to the listener. Ask what your wording makes identifiable for the listener, not whether the object exists in your own mind.
From meaning to the matching form
- ein
Ein Ordner liegt hier.
Introduce one item.
- der
Der Ordner ist leer.
Refer to the identifiable item.
- Ø
Wir brauchen Ordner.
Unspecified plural; no ordinary plural ein.
- dieser
Diesen Ordner nehme ich.
Select a particular item; accusative masculine.
Recognize useful no-article contexts
There is no ordinary plural form of ein. Ich suche Stühle. can mean that you need unspecified chairs; Ich suche die Stühle. asks for an identifiable set. A general plural can also be bare: Fahrräder brauchen Platz. A definite article can have a generalizing use too, so no article is not the only way to state a general truth.
Use a bare mass or abstract noun when no individual portion is identified: Wir brauchen Papier und Geduld. An ordinary occupation predicate often has no article: Nora ist Architektin. Compare the characterizing Nora ist eine geduldige Architektin. Personal names and many city/country names are normally bare: Minh wohnt in Berlin. Names with established articles, regional personal-name use and expanded phrases need their own check.
A changed article can signal a changed reading
Ich trinke Kaffee. presents coffee as a substance or drink generally. Ich bestelle einen Kaffee. counts one serving. Der Kaffee auf dem Tisch ist kalt. identifies a particular serving or amount. The noun is the same, but the intended unit and shared context differ. Do not label a word “always no article” merely because you learned one bare example.
| Meaning | Example |
|---|---|
| Unspecified material | Wir kaufen Holz. |
| One counted object | Wir kaufen ein Regal. |
| An identifiable object | Wir reparieren das Regal im Flur. |
Choose the form after choosing the reference
Article type, gender and case are different decisions. A new masculine object may need einen Schrank, not ein Schrank, because the sentence requires accusative. A possessive already fills the determiner role: mein Schrank, not der mein Schrank in ordinary standard wording. Vietnamese noun phrases do not use the same gender/case article system, so do not mechanically map “một” or “cái” onto every German article.
Point to a particular item with dieser
Dieser can accompany a noun: Ich nehme diesen Ordner. It can also stand alone when the noun is recoverable: Welchen Ordner? — Diesen. In the first case it is a determiner; in the second it functions as a pronoun. The ending still follows the intended gender, number and case. Do not keep an extra der before it.
| Kasus | Maskulin | Feminin | Neutrum | Plural |
|---|---|---|---|---|
| Nominativ | dieser | diese | dieses | diese |
| Akkusativ | diesen | diese | dieses | diese |
| Dativ | diesem | dieser | diesem | diesen |
| Genitiv | dieses | dieser | dieses | dieser |
Distinguish the same item from each item
Derselbe identifies the very same referent: Heute nutze ich denselben Ordner wie gestern. Write it as one word. Its first part follows der and the second has weak adjective endings: derselbe, denselben, demselben, desselben for masculine singular. Feminine forms are dieselbe, dieselbe, derselben, derselben; neuter dasselbe, dasselbe, demselben, desselben; plural dieselben, dieselben, denselben, derselben in nominative–accusative–dative–genitive order.
Jeder means each/every, so it is a quantifier rather than a demonstrative. It normally takes a singular noun: Jeder Teilnehmer bekommt eine Karte. With a noun, its masculine endings are jeder/jeden/jedem/jedes; feminine jede/jede/jeder/jeder; neuter jedes/jedes/jedem/jedes. For an ordinary plural “all participants,” use alle Teilnehmer. For a stand-alone reference to an item, make sure the gender and case are still recoverable.
Eight checks with explained answers
Try each task before opening the answer. Read the reason as well as the completed sentence.
1. Introduce a new cupboard: Im Flur steht ___ Schrank.
ein. A new singular countable item; Schrank is masculine nominative.
2. Refer back to that cupboard: ___ Schrank ist offen.
Der. The previous sentence identifies which cupboard.
3. Unspecified chairs: Wir brauchen ___ Stühle. Is there a plural ein?
Wir brauchen Stühle. No ordinary plural ein is needed. Einige would add a quantity nuance.
4. State Nora’s occupation neutrally: Nora ist ___ Architektin.
Nora ist Architektin. A plain occupation predicate commonly has no article.
5. One serving: Ich bestelle ___ Kaffee.
einen. The serving is counted; Kaffee is masculine accusative.
6. Point to a folder: Ich nehme ___ Ordner. (dieser)
diesen. Nehmen requires an accusative object; the noun is masculine.
7. Short reply: Welchen Ordner nimmst du? — ___. (dieser)
Diesen. The pronoun stands for the masculine accusative noun phrase.
8. Repair: Jede Teilnehmer nutzt den selbe Raum.
Jeder Teilnehmer nutzt denselben Raum. Jeder agrees with masculine nominative; denselben is one word in masculine accusative.
Describe a shared room clearly
Write a five-line message. Introduce one object, refer back to it, name unspecified supplies, point to one of two alternatives, and identify an item reused from yesterday. Model: Wir haben einen neuen Tisch. Der Tisch steht am Fenster. Wir brauchen Papier. Diesen Ordner nehme ich mit. Morgen benutzen wir denselben Raum. Explain each article choice before checking the endings.

Questions about this topic
Does the first mention always take ein?
No. A shared situation can already identify the object, and names, mass nouns or general plurals may have no article.
Is jeder a demonstrative?
It is a quantifier meaning each/every. Similar endings do not make its meaning the same as dieser.
