flóknu

Flóknu is a form of the Icelandic adjective flókinn, meaning “complex” or “intricate.” It is part of the inflectional system that Icelandic uses to modify adjectives according to position, definiteness, number, and case. Flóknu does not stand alone as a common dictionary entry; rather, it represents one of the endings that the word family can take in certain syntactic contexts.

In Icelandic, adjectives decline to agree with the nouns they modify. Different endings appear depending on whether the noun is definite or indefinite, and on grammatical case and number. Flóknu is typically described in linguistic resources as a possible inflected form within this paradigm, occurring in specific constructions or dialectal uses rather than as a universally dominant form in everyday speech. Because Icelandic inflection is sensitive to article presence and noun class, the exact appearance of flóknu can vary with regional usage and stylistic choice.

The root meaning remains the same across forms: the descriptor conveys that something is complex, intricate, or involved. Flóknu therefore tends to appear in contexts involving description of systems, arguments, processes, or objects that are not straightforward. In academic writing and language-learning materials, flóknu is often presented together with related forms such as flókinn and flókin to illustrate the broader pattern of adjectival inflection in Icelandic.
