aineellisia

Aineellisia is a Finnish grammatical form rather than a distinct field or concept. It is the partitive plural form of the adjective aineellinen, which means material, physical, or tangible. The stem aine- comes from aine, meaning matter or substance, and the suffix -ellinen forms adjectives. Like other adjectives in Finnish, aineellinen is declined to agree with the noun it modifies, giving forms such as aineelliset (nominative plural) and aineellisia (partitive plural).

In usage, aineellisia describes material or physical aspects of something. It is common in academic and everyday Finnish to distinguish between material factors and non-material ones. Examples include aloja such as aineellisia eroja (material differences), aineellisia resursseja (material resources), and aineellisia olosuhteita (material conditions).

A related noun is aineellisuus, which denotes the concept of materiality or physicality—sometimes used in philosophical or theoretical discussions to refer to the state or quality of being material.

Notes on grammar: adjectives in Finnish must agree with the noun in number and case. Therefore, aineellisia accompanies plural nouns in the partitive case, for example eroja or resursseja, whereas aineelliset would modify plural nouns in the nominative.

Overall, aineellisia functions as a standard inflected form used to discuss tangible or physical aspects within Finnish texts, rather than as a standalone concept with its own separate field. See also aineellisuus and the broader contrast with henkinen (mental) or epäaineellinen (non-material) contexts.
