kartioissa

Kartioissa is a Finnish grammatical form meaning “in cones.” It is the inessive plural of the noun kartio, which denotes a cone, typically a geometric cone or a cone-shaped object. The form is used when describing something located inside or within several cones, or when referring to cones collectively in a spatial sense.

Grammatically, kartioissa is formed from the stem kartio- plus the inessive plural ending -issa (with the usual vowel harmony rules of Finnish). The corresponding singular form is kartiossa (in the cone). The plural nominative of kartio is kartiot (cones), while the genitive plural is kartioiden. Thus kartioissa follows the regular pattern of Finnish cases for -io nouns.

Use and context

Kartioissa is commonly encountered in discussions of geometry, architecture, packaging, and any context where multiple cone-shaped objects are described. It can express physical location (“inside the cones”) or metaphorical placement within cone-shaped structures. Because kartio is a common -io noun, kartioissa serves as a natural example of how Finnish handles inessive plural forms for such stems.
