größtmöglichem

größtmöglichem is the dative singular inflected form of the German adjective größtmöglich, meaning maximal or as large as possible. It appears when the noun it modifies is in the dative case and no determiner is present (strong declension), or after prepositions that require the dative. Examples include mit größtmöglichem Erfolg (with the greatest possible success), in größtmöglichem Maß (in the greatest possible measure), and am größtmöglichen Umfang (at the greatest possible extent). The form is also found in other masculine or neuter dative singular contexts, such as mit größtmöglichem Aufwand or in größtmöglichem Maß.

Größtmöglich is a compound adjective formed from groß (big) and möglich (possible), used to express the upper limit of what is feasible or permissible. As with many German adjectives, its endings vary with gender, number, and article. In the dative singular without an article, the ending -em yields größtmöglichem (masculine or neuter). With a definite article or a determiner, the endings change: dem größtmöglichen Umfang, der größtmöglichen Chance, das größtmögliche Maß.

Usage of größtmöglichem tends to be formal, technical, or juridical, but it also appears in everyday language when emphasizing the maximum permissible or achievable level. Its close relatives include größtmöglich (the maximal) and the adverbial forms used in parallel constructions.

In summary, größtmöglichem is a specific inflected form of größtmöglich used in dative contexts without a determiner (or after dative-prepositions), signifying the greatest possible degree or extent.
