Regional variant
The spelling 'dermassen' is a Helvetism, meaning it is common and correct in Switzerland. In Germany and Austria, it is written 'dermaßen'.
EXAMPLE

Sentence structure
As an adverb, 'dermassen' (extremely / so) stands directly before the adjective or participle that it intensifies. It often introduces a consecutive clause with 'dass' (that), which describes the result of the high degree.
EXAMPLE

Word structure
The word comes from the old genitive form 'der Maßen', which literally means 'of this measure' or 'to this degree'. This origin helps explain why it describes an extent.
EXAMPLE
Die Musik war dermassen laut, dass man sein eigenes Wort nicht verstand.
The music was so loud that you couldn't hear yourself speak.
