German Adjective Endings: The System Taught Clearly at Last
By Lena Fischer · CEFR examiner & DaF specialistUpdated 10 min read
German adjectives take endings from just five possibilities (-e, -en, -er, -em, -es) across three patterns: weak after der-type articles, mixed after ein-type, and strong without any article. Learning them staged — nominative first, dative last — makes the system tractable.
Adjective endings are German's final boss. Secret: you need five endings, not forty-eight forms.
The 80/20 structure
| Context | Pattern | Example |
|---|---|---|
| After der/die/das | weak: -e/-en | der alte Mann |
| After ein/mein/kein | mixed | ein alter Mann |
| No article | strong (full) | altes Wasser |
Decision flowchart
- Article before the adjective?
- der-type → weak (-e nominative singular, -en almost everywhere else)
- ein-type → mixed: mirror ein's visible ending, patch gaps with strong
- No article → adjective wears the full article ending itself
Staged practice plan
- Weeks 1–2: nominative only
- Week 3: add accusative
- Month 2: dative (-m fortress)
- Genitive whenever — rarest in speech
