eiuniikki
Eiuniikki is a Finnish term formed by the negation prefix ei- and the adjective uniikki (unique). The phrase translates roughly as “not unique” and is used to describe things that are not one of a kind, lack distinctiveness, or appear in duplicates. In standard Finnish, it is more of a descriptive expression than a fixed technical term.
In use, eiuniikki appears mainly in linguistic discussion, data labeling, or informal speech to signal non-uniqueness.
There is no widely recognized organization, publication, or product officially named eiuniikki in major reference sources.
