obliiki

Obliiki is a term used in different online and fictional contexts, and it does not have a single, universally accepted definition. It appears in both speculative biology within fictional worlds and in discussions about constructed languages, leading to multiple distinct meanings depending on the setting.

The etymology is not fixed, but the coinage likely blends oblique with a diminutive -iki suffix, a combination that has appeared in fan-created worldbuilding and conlang discussions since the 2010s.

In speculative fiction, particularly in shared universes and role-playing settings, obliiki refers to a small, bioluminescent, arboreal creature. In these settings they are about 15 to 20 centimeters long, have angular body shapes, and use light patterns along with vocalizations to communicate. They are nocturnal, typically social, and live in canopy communities where they help pollinate plants and disperse seeds.

In the field of constructed languages, obliiki designates a proposed oblique-case marker used to signal indirect arguments such as recipients or instruments. It is generally presented as a feature under discussion for potential inclusion in a conlang, rather than as a feature of any widely used language.

Cultural presence: The term appears in fan glossaries, wiki pages, and tabletop RPG materials, with varying definitions depending on the setting. Because there is no authoritative standard, its meaning is defined locally within each project.
