German grammar glossary: simple explanations and examples
What does accusative mean? Why does der sometimes become den? And what is the difference between a modal verb and a modal particle?
This glossary explains the German grammar terms you will meet on Deutschable Games. Each entry gives you a short explanation, a German example with an English translation, and a next step for practice or further reading.
Use it when a game description or grammar explanation contains a word you do not know. You can read one entry, try its example aloud and then return to your game.

Noun — Nomen / Substantiv
A noun names a person, place, thing or idea. German nouns start with a capital letter, even in the middle of a sentence: die Lehrerin (the teacher), das Haus (the house), die Zeit (time).
Example: Das Kind liest ein Buch. — The child is reading a book. Both Kind and Buch are nouns.
Learn a noun together with its article and plural: das Buch, die Bücher. That gives you more useful information than learning Buch on its own.
Practice German vocabulary. Related: gender, plural.
Grammatical gender — Genus
Every German noun has a grammatical gender: masculine, feminine or neuter. The singular nominative definite articles are der, die and das. Gender is a property of the noun; it does not always match a person's gender and does not mean that objects are male or female.
Example: der Tisch, die Lampe, das Fenster — the table, the lamp, the window.
Some endings give useful clues, but learning the article with the noun is a good starting point. Remember that an article's form can also change with the noun's case.
Practice noun gender with Gender Stack.
Article — Artikel
An article accompanies a noun. Definite articles, such as der, die, das, roughly correspond to “the”. Indefinite articles, such as ein and eine, roughly correspond to “a” or “an”. Their forms depend on gender, number and case.
Example: Das ist ein Hund. Ich sehe den Hund. — That is a dog. I can see the dog.
In the second sentence, masculine der Hund becomes den Hund because it is accusative. The noun's gender has not changed.
Practice German articles. Related: accusative, determiner.
Plural — Plural / Mehrzahl
The plural is the form used for more than one person or thing. German has several plural patterns, so there is no single ending you can add to every noun. Some plurals also change a vowel with an umlaut.
Example: das Buch → die Bücher — the book → the books; die Lampe → die Lampen — the lamp → the lamps.
The nominative definite article for plural nouns is die, regardless of their singular gender. Other cases can change that article again.
Practice plurals with Plural Planes.
Determiner — Begleiter / Determinativ
A determiner comes before a noun and helps specify which thing, whose thing or what quantity you mean. Articles belong to this group, as do words such as mein (my), dieser (this) and kein (no / not a).
Example: mein Hund, dieser Hund, kein Hund — my dog, this dog, no dog.
The determiner matters when you choose an adjective ending: compare der kleine Hund and ein kleiner Hund. The exact ending also depends on case, gender and number.
Continue with adjective endings, then explore adjective-ending practice.
Adjective — Adjektiv
An adjective describes a person or thing: klein (small), schnell (fast), warm (warm). In German, an adjective before a noun usually takes an ending. When it follows sein to describe the subject, it normally stays unchanged.
Example: Das Wasser ist kalt. — The water is cold. Ich trinke kaltes Wasser. — I’m drinking cold water.
Notice kalt in the first sentence and kaltes before the noun in the second.

Adjective endings — Adjektivendungen / Adjektivdeklination
Adjective endings connect a describing word with the grammatical information in its noun phrase. The choice depends on the determiner, case, gender and number. The common endings are -e, -en, -er, -es and -em.
Example: der kleine Hund — the small dog; mit dem kleinen Hund — with the small dog; ein kleiner Hund — a small dog.
Read the whole phrase before choosing an ending. An isolated article form can have more than one grammatical use.
Try Declining Space for determiner–ending practice, and use the adjective-endings guide to connect it with complete phrases.
Declension — Deklination
Declension means changing the form of nouns, articles, adjectives or pronouns to express grammatical information such as case and number. In German, you often see these changes most clearly in the words around a noun.
Example: der kleine Hund → mit dem kleinen Hund — the small dog → with the small dog. The article and adjective change here, while Hund stays the same.
Nouns can change too: mit den Kindern — with the children. The dative plural adds -n to Kinder.
Read case and adjective endings, or explore preposition and case practice.
Case — Kasus / Fall
A case marks the grammatical role or relationship of a noun phrase or pronoun. German has four cases: nominative, accusative, dative and genitive. Verbs and prepositions can require particular cases.
Example: Der Mann hilft dem Kind. — The man helps the child. Der Mann is nominative; dem Kind is dative because helfen takes a dative object.
The case often changes the article or pronoun rather than the noun itself. Learn a whole combination, such as jemandem helfen — to help someone.
Explore German case practice. Related: nominative, accusative, dative, genitive.
Nominative — Nominativ
The nominative is the case normally used for the subject of a sentence: the person or thing the verb agrees with. You will also meet it after sein when identifying someone or something.
Example: Der Hund schläft. — The dog is sleeping. Der Hund is the subject and is nominative. Er ist ein guter Lehrer. — He is a good teacher. The phrase ein guter Lehrer is nominative too.
Start by recognizing the nominative article forms der, die, das and plural die.
Review German articles. Related: case.
Accusative — Akkusativ
The accusative is the case used for the direct object of many verbs and after certain prepositions. In the masculine singular, the definite article changes from der to den, and ein becomes einen.
Example: Ich sehe den Hund. — I can see the dog. Das Geschenk ist für meinen Bruder. — The present is for my brother.
Here, sehen takes an accusative object, and für requires the accusative. Learn both the meaning and the pattern.

Dative — Dativ
The dative is used for the recipient in many sentences and is required by certain verbs and prepositions. The singular definite articles are dem for masculine and neuter nouns and der for feminine nouns.
Example: Ich gebe dem Kind ein Buch. — I’m giving the child a book. Ich fahre mit dem Bus. — I’m taking the bus.
In the first sentence, the child is the recipient. In the second, mit requires the dative. Verbs such as helfen also take a dative object: Ich helfe dir — I’m helping you.
Practice dative and accusative patterns with Case Conveyor. Related: case.
Genitive — Genitiv
The genitive often expresses possession or a relationship between nouns. You also meet it after some prepositions. Masculine and neuter nouns commonly add -s or -es in the singular genitive.
Example: die Tür des Hauses — the door of the house; das Fahrrad meiner Schwester — my sister’s bicycle.
You will encounter the genitive especially in written German. In conversation, some relationships are also expressed with von and the dative, depending on the context and style.
Continue with case and declension. For a fuller explanation, explore How German Grammar Works.
Preposition — Präposition
A preposition connects a noun phrase or pronoun with information such as place, time, direction or a relationship. German prepositions require particular cases; some always take one case, while others depend on their use.
Example: mit dem Zug — by train; für meine Freundin — for my friend. Mit takes the dative and für takes the accusative.
Learn a preposition together with a complete phrase. That makes its case easier to connect with something you can say.
Play Preposition Survivor to practice fixed accusative and dative prepositions. For the separate location/destination pattern, read two-way prepositions.
Two-way prepositions — Wechselpräpositionen
The two-way prepositions are an, auf, hinter, in, neben, über, unter, vor and zwischen. In their spatial uses, the dative typically describes where something is or happens, while the accusative describes a destination or change of spatial relationship.
Example: Ich laufe im Park. — I’m running in the park. Ich laufe in den Park. — I’m running into the park.
Both sentences involve movement. The difference is movement within a location versus movement into it. “Movement always means accusative” is therefore an unreliable rule. Non-spatial uses need to be learned in their own context.
Read the prepositions and cases guide. Preposition Survivor focuses on fixed-case prepositions and does not currently practice this distinction.
Pronoun — Pronomen
A pronoun can stand in place of a noun phrase or refer to a person or thing. German personal pronouns include ich, du, er, sie, es, wir and ihr. Their forms can change with case.
Example: Ich sehe den Mann. Ich sehe ihn. — I can see the man. I can see him. Ich helfe ihm. — I’m helping him.
Here, ihn is accusative and ihm is dative. The verb helps determine which form you need.
Practice sentence patterns with Sentence Flashback. Related: accusative, dative.
Verb — Verb
A verb expresses an action, event or state, such as lernen (to learn), regnen (to rain) or sein (to be). In a sentence, its form can show who is involved and how the event is presented in time.
Example: Ich lerne Deutsch. — I’m learning German. Wir lernen Deutsch. — We’re learning German.
The subject changes from ich to wir, so the verb changes from lerne to lernen.

Infinitive — Infinitiv
The infinitive is the basic form of a verb, usually the form listed in a dictionary. Most German infinitives end in -en, such as machen or gehen; some end in -n, such as wandern.
Example: Ich kann schwimmen. — I can swim. Kann is conjugated, while schwimmen is an infinitive.
A common pattern with a modal verb is a conjugated modal near the beginning of a statement and an infinitive at the end.

Conjugation — Konjugation
Conjugation means changing a verb's form to match grammatical information such as person, number, tense or mood. When you first learn German, this often means choosing the form that goes with ich, du, er or another subject.
Example: ich spiele, du spielst, sie spielt, wir spielen — I play, you play, she plays, we play.
Some verbs also change their stem: ich fahre, but du fährst. Learn these forms with a short example sentence.
Practice conjugation with Flapjugation. Related: present tense.
Present tense — Präsens
The German present tense describes current situations, habits and general facts. With a suitable time expression, it can also refer to the future. German normally uses the same present form where English distinguishes “I learn” from “I am learning”.
Example: Ich lerne jeden Tag Deutsch. — I learn German every day. Morgen fahre ich nach Berlin. — Tomorrow I’m going to Berlin.
Look at the whole sentence, including words such as jeden Tag or morgen, to understand the time reference.
Modal verb — Modalverb
A modal verb adds meanings such as ability, permission, necessity or intention to another verb. The core German modal verbs are dürfen, können, mögen, müssen, sollen and wollen. You will also often meet möchte, a Konjunktiv II form of mögen used to express a wish politely.
Example: Ich kann schwimmen. — I can swim. Du musst heute arbeiten. — You have to work today.
In these statements, the modal is conjugated and the other verb appears as an infinitive at the end.
Practice modal verbs with Modal Combat. Related: Konjunktiv II. A modal particle is a different kind of word.
Auxiliary verb — Hilfsverb
An auxiliary is a helping verb used with another verb to build a grammatical form. German uses haben and sein to form the Perfekt. Werden is used in other constructions, including the future and the passive.
Example: Ich habe gekocht. — I cooked / have cooked. Sie ist angekommen. — She arrived / has arrived.
The auxiliary is conjugated. In these examples, gekocht and angekommen are past participles.
Practice haben or sein with Saber Perfekt. Related: Perfekt, past participle.
Past participle — Partizip II
The past participle is a verb form used in constructions such as the Perfekt. Common examples are gemacht (done / made), gelesen (read) and gegangen (gone). Not every participle begins with ge-.
Example: Ich habe das Buch gelesen. — I read / have read the book. Wir haben telefoniert. — We spoke / have spoken on the phone.
Learn the participle together with its auxiliary: hat gelesen, ist gegangen. The participle is one part of the complete tense construction.
Try auxiliary–participle matching in Saber Perfekt. Related: Perfekt.
Perfekt — conversational past tense
The Perfekt is a German past tense formed with a conjugated form of haben or sein plus a past participle. It is common when talking about past events in conversation. Depending on context, its English equivalent may be a simple past or a present perfect.
Example: Gestern habe ich gekocht. — Yesterday I cooked. Wir sind nach Hause gegangen. — We went home.
Most verbs use haben. Many verbs of change of place or state use sein, as do sein, bleiben and werden. Some verbs vary with meaning or construction, so learn complete examples.
Practice auxiliary choice with Saber Perfekt or explore past-tense practice.
Präteritum — simple past tense
The Präteritum is a German past tense formed through the verb itself, without the haben/sein + participle structure of the Perfekt. It is common in written narratives. Forms of sein, haben and modal verbs also appear frequently in everyday speech.
Example: Ich war müde und hatte keine Zeit. — I was tired and had no time. Ich konnte nicht kommen. — I couldn’t come.
Usage varies with region, verb and context. You do not need to replace every conversational Perfekt sentence with Präteritum.
Explore German past-tense practice. Modal Combat includes past forms of modal verbs; it is not a comprehensive Präteritum course.
Konjunktiv II — hypothetical and polite forms
Konjunktiv II is a grammatical mood used for hypothetical situations, wishes and polite requests. Familiar forms include wäre, hätte, könnte and würde with an infinitive. It is not simply another name for the past tense.
Example: Wenn ich Zeit hätte, würde ich mitkommen. — If I had time, I would come along. Könnten Sie mir helfen? — Could you help me?
The first sentence imagines a situation; the second makes a request more polite.
Practice Konjunktiv II with Modal Combat. Related: modal verb.
Separable verb — trennbares Verb
A separable verb has a prefix that separates from the conjugated verb in certain sentence structures. In a typical present-tense main clause, the conjugated part appears near the beginning and the prefix goes at the end.
Example: Ich rufe dich morgen an. — I’ll call you tomorrow. The infinitive is anrufen.
With a modal verb, the infinitive stays together: Ich möchte dich anrufen — I’d like to call you. The position depends on the sentence structure.
Practice separable-verb word order with Sentence Flashback. Related: infinitive, word order.
Word order — Wortstellung / Satzstellung
Word order is how the parts of a sentence are arranged. In a standard German declarative main clause, the conjugated verb comes in the second position. That means the second sentence element, not necessarily the second word.
Example: Am Montag lerne ich Deutsch. — On Monday I’m learning German. Am Montag fills the first position; lerne is in the second.
Other verb parts often appear later: Ich habe gestern Deutsch gelernt. — I studied German yesterday. This separation is often called the Satzklammer, or sentence bracket.
Practice word order with Sentence Flashback or read the word-order guide.
Main and subordinate clauses — Hauptsatz und Nebensatz
A main clause can normally stand as a sentence on its own. A subordinate clause adds information within a larger sentence. In standard subordinate clauses introduced by words such as weil or dass, the conjugated verb normally comes at the end.
Example: Ich bleibe zu Hause, weil ich krank bin. — I’m staying at home because I’m ill.
In the main clause, bleibe is in second position. In the weil clause, bin is at the end. A comma separates the clauses.
Practice clause patterns with Sentence Flashback. Related: word order.
Negation — Verneinung
Negation makes a statement negative. German commonly uses nicht and kein. Use kein to negate a noun phrase that would otherwise have ein/eine or no article. Nicht can negate verbs, adjectives and other parts of a sentence.
Example: Ich habe kein Auto. — I don’t have a car. Das Auto ist nicht neu. — The car is not new.
The position of nicht depends on what you are negating. Kein changes its form according to gender, case and number.
Practice negation in Sentence Flashback. Related: determiner.
Modal particle — Modalpartikel
A modal particle adds a speaker's attitude, expectation or conversational tone. Common examples include doch, mal, ja and halt. Their meaning depends strongly on context, and they often have no single direct English translation.
Example: Warte mal! — Wait a moment! Here, mal makes the request sound more conversational. Das weißt du doch. — You know that, after all. Here, doch appeals to something the speaker expects the listener to know.
These words can have other functions elsewhere. Their use in a sentence matters more than a one-word translation.

CEFR levels: A1, A2 and B1 — GER-Sprachniveaus
The Common European Framework of Reference for Languages, or CEFR, describes language ability using levels from A1 to C2. Broadly, A1 covers basic familiar communication, A2 expands everyday exchanges, and B1 involves more independent communication about familiar matters.
A game's level label helps you judge whether its language may suit you. It is not a test result, certificate or promise that completing the game gives you that level. Different skills can develop at different speeds.
Example: Knowing der, die, das is a useful foundation, but reaching a CEFR level also involves using and understanding language in wider situations.
