kemiallisia

Kemiallisia is the plural partitive form of the Finnish adjective kemiallinen, meaning chemical. It is used to describe plural, indefinite nouns such as substances, reactions, or properties. For example: kemiallisia aineita (chemical substances), kemiallisia reaktioita (chemical reactions), kemiallisia yhdisteitä (chemical compounds). In phrases like "kemiallisia aineita tarvitaan" the partitive signals an indefinite amount or quantity.

In Finnish grammar, adjectives agree with the noun in number, case, and definiteness. The form kemiallisia is therefore used when the described items are not yet counted or are considered in a mass or partial sense. The corresponding nominative plural is kemialliset, e.g., kemialliset aineet meaning "the chemical substances." The adverbial form is kemiallisesti (chemically).

Etymology and usage: The noun kemia (chemistry) and its derivatives come from borrowing from European languages for chemistry, commonly linked to Swedish kemi and French chimie; the lineage traces back to Greek khēmía (alchemy). The adjective kemiallinen, and by extension its inflected forms such as kemiallisia, reflect this linguistic heritage.
