aistittavien

Aistittavien is a Finnish inflected form that functions as the genitive plural of the adjective aistittava, meaning perceivable or capable of being perceived by the senses. The form is used when referring to objects, properties, or phenomena that can be sensed, and it typically appears in phrases describing such perceivable things in a genitive construction.

In practice, aistittavien is used to modify a following noun in genitive, indicating that the described items are perceivable. Common collocations include aistittavien ominaisuuksien (of perceptible properties), aistittavien esineiden (of perceivable objects), or aistittavien ilmiöiden (of perceivable phenomena). The nominative plural of the base adjective is aistittavat, while the partitive plural is aistittavia, and the genitive plural is aistittavien, reflecting Finnish's system of adjective declension.

Etymology traces the word to the stem aisti- (sense) and the -ttava suffix, which forms adjectives meaning "capable of" or "relating to." The ending -ien marks the genitive plural, a common pattern for many Finnish adjectives in this form.

Usage notes: aistittavien appears in formal or academic Finnish, particularly in discussions of perception, epistemology, or descriptive analysis of perceptible characteristics. It is not a standalone noun but a grammatical form that signals a relationship to perceivable things within a noun phrase.
