German adjective endings are one of the biggest stumbling blocks past A2. The declension table interlocks three patterns (strong, weak, mixed) with 16 case/gender/number cells each - 48 forms in total - and high-volume reps under light time pressure are one of the most reliable ways we know of to make adjective endings feel like grammar instead of maths.
There are three German declension patterns: strong (no article - endings carry the case info), weak (after definite articles - endings are mostly -e and -en), and mixed (after indefinite articles like ein/kein - a hybrid). Each pattern interacts with gender, number, and case, which is what makes the table so intimidating on paper.
Drilling endings in motion can build procedural memory - the same kind of memory you use to drive - so the right ending tends to fire automatically once the determiner and noun in front of you show the case, gender and number. For many learners, a few minutes a day moves them from frozen-at-the-table to fluent-mid-sentence faster than they expected.
Memorising the table on its own rarely sticks. A more practical approach is to drill endings inside complete noun phrases (mit einem neuen Fahrrad) until the right one tends to fire automatically. The five endings are -e, -en, -er, -es and -em, and the attributive ending sits between the determiner and the noun.
Strong (no article), weak (after definite articles like der/die/das), and mixed (after indefinite articles like ein/kein). The pattern depends on whether and which article precedes the adjective.
