Theoretischem

Theoretischem is a declined form of the German adjective theoretisch, meaning theoretical. It is not a standalone lexical item but a morphologically inflected form used when the adjective modifies a masculine or neuter noun in the dative case, typically without a determiner.

In standard German, adjectives in the dative singular without an article take the strong ending -em. This yields forms such as theoretischem Hintergrund (theoretical background) and theoretischem Sinn (theoretical sense). When a determiner is present, the endings change according to the declension pattern (for example, dem theoretischen Hintergrund or im theoretischen Sinn). The form theoretischem therefore commonly appears in phrases after prepositions that require the dative, especially in formal or written language.

The form is widely used in academic, scientific, and theoretical writing, where adjectives frequently describe concepts, models, or frameworks. It is part of the broader system of German adjective declension, where the ending of theoretisch changes to reflect case, gender, and number of the noun it modifies.

Etymologically, theoretisch derives from the noun Theorie (theory) plus the suffix -isch, forming an adjective that denotes relation to theory. The specific ending -em in theoretischem signals its grammatical role rather than a change in meaning.

In summary, theoretischem is the dative singular form of theoretisch used without a determiner to describe a masculine or neuter noun in contexts such as mit theoretischem Hintergrund or in theoretischem Sinn, reflecting German strong declension in the dative.
