Chemiallisen

Chemiallisen is not a standard Finnish term. The correct Finnish adjective meaning “chemical” is kemiallinen. The form kemiallisen is the genitive singular of kemiallinen and is used to indicate possession or relation to a chemical substance, for example in phrases like kemiallisen aineen koostumus or kemiallisen reaktion tuotteet.

In Finnish, adjectives decline to agree with the noun they modify. For kemiallinen, typical forms include nominative singular kemiallinen, partitive singular kemiallista, genitive singular kemiallisen, inessive singular kemiallisessa, and plural forms such as kemialliset (nominative) or kemiallisten (genitive plural). The genitive singular kemiallisen is commonly found in technical, scientific, and educational writing to denote “of the chemical …” or “the chemical’s …”.

Etymology: kemiallinen derives from kemia (chemistry) with the adjectival suffix -llinen, which forms words meaning “pertaining to” or “characteristic of.” The Finnish word kemia itself is a loanword from other European languages for the science of chemistry, with deeper roots tracing back to classical terms for chemical knowledge.

Usage notes: When writing in Finnish, use kemiallinen and its correct inflected forms rather than a form like chemiallisen, which is typically a misspelling or nonstandard hybrid. The term kemiallinen is widely used across science, industry, education, and media to describe properties, processes, substances, and concepts related to chemistry.
