öflugasti
Öflugasti is a word in the Icelandic language meaning “the most powerful.” It is the superlative form of the adjective öflugur, which conveys power, strength, or influence. Öflugasti is used to compare three or more entities and can function either as a modifier before a noun or as a predicate adjective.
In Icelandic, adjectives inflect for gender, number, and case, so the form öflugasti adapts to the noun
Etymology traces öflugur to the broader Nordic-rooted vocabulary for strength and capability; öflugasti inherits this lineage
