upplýstir

Upplýstir is the masculine plural nominative form of the Icelandic adjective upplýstur, meaning "enlightened," "informed," or "knowledgeable." It is used to describe people or groups that have information, awareness, or understanding, or objects that have been clarified or illuminated. The form is part of a broader family of adjectives derived from the verb upplýsa, “to inform” or “to illuminate.”

The adjective upplýstur comes from upplýsa, with the typical adjectival suffix -stur. The corresponding feminine plural is upplýstar, and the neuter plural is upplýst. In modern Icelandic, upplýstir is primarily a grammatical inflection rather than a commonly used standalone term; speakers typically use upplýstur (singular) or other phrasing to describe a group of informed people.

Usage examples include: “Upplýstir borgarar tóku þátt í umræðunni” (Informed citizens participated in the discussion). In practice, upplýstir functions as an inflected form that must agree with the noun it describes in gender and number, while the related noun upplýsing means “information.”

Related terms include upplýsing (information), upplýsa (to inform), and upplýstur (enlightened).
