German Grammar, Explained Clearly

Use the accusative (Akkusativ) for the direct object — the thing being acted on — and the dative (Dativ) for the indirect object — usually the recipient. Compare “Ich sehe den Mann” (I see the man, accusative) with “Ich gebe dem Mann das Buch” (I give the man the book, dative).

German has six modal verbs — können (can), müssen (must), dürfen (may), sollen (should), wollen (want), and mögen (like). They express ability, necessity, permission, or wish, and they send the main verb to the end of the sentence in its infinitive form: “Ich kann Deutsch sprechen.”

Both describe the past. Use the Perfekt (“Ich habe gegessen”) in everyday speech and informal writing; use the Präteritum (“Ich aß”) in written narration, news, and books. The big exceptions are sein, haben, and the modal verbs, whose Präteritum (war, hatte, konnte) is normal even when speaking.

Der die das are the three German definite articles meaning 'the'. Der marks masculine nouns, die marks feminine nouns and all plurals, and das marks neuter nouns. Certain noun endings reliably predict gender: -ung, -heit, -keit always take die, while -chen and -lein always take das.

Wechselpräpositionen are nine German prepositions that take either accusative or dative case. Use accusative with wohin (where to) for movement or direction: in die Küche. Use dative with wo (where) for static location: in der Küche. The nine are an, auf, hinter, in, neben, über, unter, vor, zwischen.

German word order follows strict rules: the conjugated verb occupies position 2 in statements (V2), moves to position 1 in yes/no questions, and shifts to the end in subordinate clauses introduced by weil, dass, wenn, or ob. Adverbials follow the TeKaMoLo sequence: temporal, causal, modal, local.

German adjective endings change based on the article type and case. After definite articles (der/die/das), use weak endings -e or -en. After indefinite articles (ein/eine), the adjective shows gender with -er, -e, or -es. Without articles, adjectives take strong endings that signal the noun's gender and case.

German cases are four grammatical forms that show a noun's role in a sentence: Nominativ for subjects, Akkusativ for direct objects, Dativ for indirect objects, and Genitiv for possession. Each case changes the article and sometimes the noun ending, such as der Mann, den Mann, dem Mann, des Mannes.

Konjunktiv 2 expresses politeness, wishes, and hypothetical situations in German. Form it with würde + infinitive for most verbs, or use special forms: hätte (would have), wäre (would be), könnte (could), müsste (would have to), and sollte (should).

German separable verbs split into two parts in main clauses: the conjugated verb stays in second position, and the prefix moves to the end of the sentence. For example, aufstehen becomes Ich stehe auf. In subordinate clauses and perfect tense, the verb stays together.

German negation nicht kein follows clear patterns: use nicht to negate verbs, adjectives, and adverbs, and use kein to negate nouns that have an indefinite article or no article. The word kein declines like ein (keinen, keine, kein, keine in plural).

The German comparative adds -er to adjectives (schneller, größer), while the superlative uses am plus -sten (am schnellsten) or der/die/das plus -ste. Many common adjectives take an umlaut (alt → älter), and a few are irregular (gut → besser → am besten).

The German future tense (Futur I) is formed with the conjugated auxiliary verb werden plus an infinitive at the end of the sentence: ich werde fahren, du wirst machen, er wird sein. Germans often use present tense with a time expression instead of Futur I in everyday speech.

German relative clauses describe a noun in more detail and begin with a relative pronoun like der, die, or das. The pronoun matches the gender and number of the noun it refers to, while its case depends on its role within the relative clause. The conjugated verb always moves to the end of the clause.

German reflexive verbs require a reflexive pronoun that refers back to the subject. The accusative pronouns are mich, dich, sich, uns, euch, sich. When a second object is present, use dative forms: mir, dir, sich, uns, euch, sich. True reflexive verbs like sich freuen always need a pronoun.

The German passive voice shifts focus from the doer to the action itself. Form it with werden plus the Partizip II: Das Haus wird gebaut. Only werden conjugates; the Partizip II stays at the end. Use von + Dativ to name the agent.

The German imperative is the command and request form. It has three versions: du-form (informal singular), ihr-form (informal plural), and Sie-form (formal). For du, drop the -st ending: Komm!, Geh! For ihr, use the conjugated verb without the pronoun: Kommt! For Sie, invert verb and pronoun: Kommen Sie!

The German genitive case expresses possession and belonging, as in das Auto des Mannes. Masculine and neuter nouns add -s or -es, while articles change to des (masculine/neuter), der (feminine/plural), or eines/einer. Certain prepositions like wegen, trotz, and während always require genitive.

Konjunktiv 1 is the German subjunctive mood used primarily for indirect speech. It is formed with the verb stem plus endings -e, -est, -e, -en, -et, -en. For example: er habe, sie komme, er sei. It appears frequently in news reports and formal writing to report what someone said without endorsing it.

German subordinating conjunctions like weil, dass, wenn, and obwohl introduce subordinate clauses where the conjugated verb moves to the end. For example: Ich bleibe zu Hause, weil ich krank bin. A comma always separates the main clause from the subordinate clause.

German two-part conjunctions connect words, phrases, or clauses using paired elements: entweder…oder (either…or), nicht nur…sondern auch (not only…but also), sowohl…als auch (both…and), weder…noch (neither…nor), zwar…aber (admittedly…but), and je…desto (the more…the more). Each pair follows specific word-order rules.

German n-declension applies only to masculine nouns that add -n or -en in all cases except nominative singular. Common groups include nouns ending in -e (der Junge → den Jungen), those with -ent/-ant/-ist/-at (der Student → den Studenten), many nationalities (der Franzose → den Franzosen), and several animals (der Löwe → den Löwen).

German time prepositions indicate when something happens. Use am with days and times of day (am Montag, am Abend), um with clock times (um 9 Uhr), im with months and seasons (im Januar, im Winter), and seit with durations that continue (seit einem Jahr). Most temporal prepositions take the dative case.
