Selsiusillä

Selsiusillä is a Finnish term whose exact meaning is not established in standard usage. Grammatically, it would be formed by attaching the adessive plural suffix -llä to the proper noun Selsius, yielding Selsiusillä, which would indicate location or context related to Selsius, as in “on Selsius” or “at Selsius.” Because the base is not a common Finnish word, the form appears almost exclusively in fictional, speculative, or experimental writing, where Selsius may denote a place, organization, or concept.

In linguistic terms, selsiusillä demonstrates how Finnish morphology can produce locative forms from proper nouns. The same pattern can apply to other named places or groups, producing forms such as Xllä or Xillä, depending on the base.

Usage and examples: In fiction, Selsiusillä can denote a setting: “Tutkimus sijoittui Selsiusillä.” In academic or descriptive contexts, it might appear when discussing places named in a hypothetical world.

Notes: As of now, there is no widely used or official meaning of selsiusillä outside creative or fringe contexts. Readers should interpret it based on the surrounding text, and be careful not to confuse it with Celsius-related terms.
