akvörðuð
Akvörðuð is a word form encountered in discussions of Icelandic morphology. It is typically described as the feminine singular past participle form of a hypothetical verb akvörða, which would mean to forewarn or to give advance notice. The term is not widely attested in standard dictionaries or contemporary Icelandic texts, and there is no stable, widely accepted gloss for the lemma akvörða. As a result, akvörðuð is mainly cited as an illustrative example of how Icelandic participles can be formed, rather than as a common lexical item with a fixed meaning.
In usage, akvörðuð does not appear in everyday language because the presumed verb akvörða is not established
Etymology: the form akvörðuð is constructed from a stem akvörða followed by the standard feminine singular
