aisteissa

Aisteissa is a Finnish linguistic term used to describe a specific inflected form of the noun aisti, which means sense or perception. The literal translation is "in the senses." In Finnish grammar, the inessive case marks location or state of being "in" something, and aisteissa is the form that can refer to senses in a plural or collective sense within that framework. The term is primarily deployed in linguistic descriptions of inflection patterns rather than in everyday speech.

In scholarly usage, aisteissa appears in grammars and language descriptions as an example of how nouns ending in -i behave under the inessive case and pluralization. It is not a common everyday word outside academic contexts and is mainly encountered in discussions of morphology, syntax, or Finnish phonology. When it does appear in literature, it is typically in a descriptive or illustrative capacity rather than as a functional part of ordinary dialogue.

Because it is a technical form rather than a semantic category, aisteissa does not denote a separate concept of sensory experience. Instead, it serves as a surface form for analyzing how sensory nouns flex in Finnish. Related topics include aisti (sense), inessive case (-ssa/-ssä), and broader Finnish noun inflection and morphology.
