bestätigtem

Bestätigtem is a German inflected form derived from the past participle confirming, bestä­tigt, used as an attributive adjective. It is not a standalone word with its own meaning; rather, it is the form the participle takes when it modifies a noun and the surrounding grammar requires a dative masculine or neuter singular ending.

In German, adjectives that stand in attributive position decline according to case, gender, and definiteness. The form bestä­tigtem appears in the dative singular for masculine or neuter nouns when the article or determiner does not provide full case indication, or under strong declension (for example after prepositions such as mit). Thus you can encounter phrases like mit bestätigtem Datum or mit bestätigtem Beleg, meaning “with a confirmed date” or “with a confirmed receipt.”

Usage of bestätigtem is common in formal or administrative language, such as contracts, reports, or official correspondence, where precision about the status of information or documents is important. The form contrasts with other declensions of the same participle, such as bestätigte (nominative or accusative feminine) or bestätigten (genitive or plural forms, or after determiners).

In summary, bestätigtem is the dative singular form used when the participle from bestätigen functions adjectivally in contexts that require a strong/undetermined ending, signaling that something has been confirmed. See also German grammar, participles as adjectives, and declension patterns.
