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.
