Adjectives:Adjektive nach Der-Wörtern
While predicate adjectives are not part of the der-word adjectives, it is important to discuss briefly their position and use. Predicate adjectives take the most basic, unaltered form of the adjective, and don't take any endings unless they are in the comparative or superlative forms. These adjectives are linked to the nouns they describe with a verb such as sein, werden, heißen.
Attributive adjectives after der-words
Adjectives that follow definite articles (der, die, das, den, dem, etc.) or the other der-words dieser, jeder, jener, mancher, solcher, welcher, alle and precede the nouns they describe, take so-called weak endings. These endings apply whether the adjective is in the basic form or in the comparative or superlative forms.
To determine the correct adjective ending, determine the gender of the noun the adjective describes (masculine, feminine, neuter or plural) or number (in the case of plural nouns), then determine what case the noun is in the sentence or phrase (nominative, accusative, dative, or genitive).
Changes in the basic form
When adjectives that end in -el, -en or -er in the basic form get an adjective ending, they drop the -e- before the final consonant and add the endings to this new form (see the example with dunkel).
Some adjectives with foreign origins (many of these words end in a vowel) do not take adjective endings: lila, pink, rosa, beige, prima, super, etc
