erfolgreichem

Erfolgreichem is a grammatical form in the German language. It is the dative singular form of the adjective erfolgreich when declined without a determiner (the strong declension). It describes masculine and neuter nouns in the dative case and is not a separate concept or proper noun, but a morphological ending that signals case, gender, and number.

Etymology: The form is built from the base adjective erfolgreich, meaning “successful.” The ending -em marks the dative singular for masculine and neuter nouns in the strong declension, following standard German adjective inflection rules.

Usage: The form appears in phrases where a noun in the dative case is modified by a bare adjective. Examples include: Mit erfolgreichem Vorgehen konnte das Team das Ziel erreichen (neuter Vorgehen). In erfolgreichem Umfeld arbeiten Forscher oft effizienter (neuter Umfeld). Another example is Mit erfolgreichem Einsatz konnte der Feuerwehrtrupp den Brand eindämmen (masculine Einsatz).

Relation to other declensions: When a definite article is present, the adjective takes a different ending in the dative (for example, dem erfolgreichen Vorgehen). The form erfolg­erichem belongs to the strong declension, whereas with a determiner that supplies the ending, the weak or mixed declension would apply and yield a different ending.
