Predicative vs. Attributive Adjectives

English speakers rarely have to think about where an adjective sits in a sentence, because old looks identical in the house is old and the old house. In German, however, that single change in position decides whether an adjective stays completely bare or needs a grammatical ending.

In German, an adjective functions in one of two main ways—predicatively or attributively—and mastering this split at A1 saves you from the single most common adjective mistake beginners make.

1. Predicative Adjectives (No Endings!)

When an adjective follows a linking verb—most importantly sein (to be), werden (to become), or bleiben (to stay/remain)—and describes the subject, it is a predicative adjective (prädikatives Adjektiv). Predicative adjectives receive no ending whatsoever, regardless of the noun’s gender or number:

• Der Mann ist alt. (The man is old. — masculine singular: der Mann)
• Die Frau ist alt. (The woman is old. — feminine singular: die Frau)
• Das Haus ist alt. (The house is old. — neuter singular: das Haus)
• Die Kinder sind alt. (The children are old. — plural: die Kinder)

Notice that alt remains completely unchanged in every single sentence! Even if you swap in werden or bleiben, nothing is added to the adjective:

• Das Wetter wird kalt. (The weather is getting cold. — das Wetter)
• Die Suppe bleibt warm. (The soup stays warm. — die Suppe)
• Unsere Nachbarn sind sehr freundlich. (Our neighbors are very friendly. — die Nachbarn)

Adverbial Use Also Takes No Ending

German does not add a special suffix like English -ly to turn adjectives into adverbs. When an adjective modifies an action verb rather than a noun, it also uses the bare base form:

• Der Zug fährt schnell. (The train travels fast. — der Zug)
• Du sprichst sehr deutlich. (You speak very clearly.)

2. Attributive Adjectives (Endings Required!)

When an adjective stands directly before a noun, it is an attributive adjective (attributives Adjektiv). Because it belongs inside the noun phrase, it must take a grammatical ending that agrees with the noun’s gender, number, and case:

• der alte Mann (the old man — masculine nominative, der Mann)
• eine alte Frau (an old woman — feminine nominative, die Frau)
• ein altes Haus (an old house — neuter nominative, das Haus)
• die alten Kinder (the old children — plural nominative, die Kinder)

Look closely at ein altes Haus versus Das Haus ist alt. In the first phrase, ein alone could be masculine or neuter, so the adjective steps in with -es to signal that das Haus is neuter. In the second sentence, alt stands after ist, so no signal is needed and adding -es would be ungrammatical.

How German Chooses the Attributive Ending

Once you know an adjective stands directly before a noun, the exact ending (-e, -en, -er, -es, or -em) depends on what kind of word comes before the adjective. German sorts attributive adjectives into three declension patterns:

1. Weak declension — after der, die, das, dieser, jeder, welcher (definite articles that already show case and gender clearly): das schöne Haus (the nice house).
2. Mixed declension — after ein, kein, or possessives like mein, dein, ihr (where masculine and neuter nominative need a gender signal): ein kleines Zimmer (a small room, das Zimmer).
3. Strong declension — when there is no article before the noun at all: kaltes Wasser (cold water, das Wasser).

Small Spelling Changes Before Endings

Most adjectives simply attach their ending straight to the dictionary form (neu → neue, klein → kleines). Three frequent patterns adjust their stem slightly as soon as an attributive ending is added:

• Adjectives ending in -el drop the -e-: dunkel (dark) → eine dunkle Nacht (die Nacht, a dark night).
• Adjectives ending in -er after a vowel often drop the -e-: teuer (expensive) → ein teures Handy (das Handy, an expensive phone).
• The adjective hoch drops its -c-: Der Berg ist hoch. (predicative) vs. der hohe Berg (attributive, der Berg).

Adjectives That Stay Unchanged Even Before a Noun

A handful of words resist declension even in attributive position:

• Color adjectives borrowed from nouns/French: lila (purple) and rosa (pink) take no endings in standard German: ein lila Pullover (der Pullover, a purple sweater), eine rosa Blume (die Blume, a pink flower).
• City and region adjectives ending in -er: Always capitalized and never declined: der Berliner Bahnhof (der Bahnhof, the Berlin train station), ein Wiener Café (das Café, a Viennese café).
• Colloquial invariables: Words like super, prima, or klasse are normally kept uninflected: eine super Idee (die Idee, a great idea).

Common Mistakes: Wrong vs. Right

Once you feel confident spotting whether an adjective sits after a linking verb or before a noun, move on to comparative and superlative forms—where you will see the same predicative-versus-attributive split in action (am schnellsten vs. der schnellste Zug).
