angemessenerem
Angemessenerem is not a standalone lexical entry in standard German. It is best understood as a declined inflected form that can arise from the adjective angemessen in the comparative degree (angemessener) when it is declined for case, number and article in a sentence. In German, adjectives change their ending according to the article that precedes the noun and the grammatical case. The basic forms are angemessen (positive), angemessener (comparative), and am angemessensten (superlative). Depending on whether the noun is preceded by a definite article, an indefinite article, or no article, the attributive adjective takes different endings, for example: der angemessene, dem angemessenen, das angemessene, einen angemessenen, einem angemessenen, ein angemessenes, usw. The exact endings for the comparative stem differ with position and emphasis.
