Adverbial Derivations with "-ermaßen"

In German, add the suffix -ermaßen to certain adjectives and past participles to create adverbs that express established facts, admissions, or necessities. This suffix works much like "-ly" or "in a ... manner" in English.

Custody is known to be difficult.
Das Sorgerecht ist bekanntermaßen schwierig.

Like all adverbs, words ending in -ermaßen don't change their endings. They can sit in the middle of a sentence, or at the very beginning for emphasis (which pushes the subject directly after the verb).
