aineellisiin

Aineellisiin is the illative plural form of the Finnish adjective aineellinen, meaning material or physical. It is used to modify a plural noun in the illative case, generally indicating movement toward or involvement with tangible aspects. In English, it corresponds to phrases like “into the material” or “to material/physical [aspects].” The form is encountered in contexts that discuss tangible, corporeal, or observable phenomena as opposed to abstract or immaterial ones.

Formation and grammar: The base stem of the adjective is aineellinen. To express the illative plural, the ending -isiin is added, resulting in aineellisiin. This form accompanies plural nouns in illative case, for example aineellisiin oloihin (into material conditions), aineellisiin resursseihin (into material resources), or aineellisiin ominaisuuksiin (into material properties). The construction follows standard Finnish agreement rules: the adjective agrees with the number (plural) and case (illative) of the noun it modifies.

Usage notes: Aineellisiin is most common in formal, academic, or policy-related language where discussions concern physical, tangible, or surface-level aspects. It contrasts with forms describing non-material or abstract aspects, such as henkisiin or aineettomiin when appropriate. While the form is productive in Finnish, it tends to appear most often in written text rather than everyday speech.
