geeignetem
Geeignetem is the dative singular form of the German adjective geeignet, which means suitable or appropriate. In German, adjectives inflect for case, gender, and number, and they change form depending on whether they are preceded by a definite article, an indefinite article, or no article at all. The form geeignetem appears in the dative singular before masculine or neuter nouns when the adjective carries the strong inflection (i.e., without a determiner that would require a weaker ending).
- mit geeignetem Werkzeug (with suitable tool) — neuter noun in the dative case
- mit geeignetem Mann (with a suitable man) — masculine noun in the dative case
- zu geeignetem Zweck (for a suitable purpose) — masculine noun in the dative case
For contrast, in the nominative neuter singular you would typically see geeignetes or after a definite article
The adjective geeignet comes from the verb eignen with the prefix ge-, a common way German forms
