Kaasumaisten

Kaasumaisten is a Finnish adjective form used to describe substances or phenomena with gaseous characteristics. It is formed from the noun kaasu (gas) with the adjective suffix -mainen, and kaasumaisten represents the plural inflected form used when describing plural nouns, for example kaasumaisten aineiden pitoisuus (the concentration of gaseous substances) or kaasumaisten ilmiöiden tutkimus (the study of gaseous phenomena). In scientific and technical literature, kaasumaisten is common in fields such as geology, chemistry, meteorology, and environmental science, where the presence or behavior of gases within materials or systems is relevant. The term tends to appear in formal or specialized contexts rather than everyday language.

Usage notes: kaasumaisten is primarily a technical and descriptive term. In general writing, speakers may prefer more common expressions, but the form is standard in Finnish grammar when modifying plural nouns.

Etymology and related forms: the word is built from kaasu plus the adjective-forming suffix -mainen. Related forms include kaasumainen (gaseous), kaasumaisuus (gaseousness), and kaasuminen (gasification or becoming gaseous). The plural form kaasumaisten is used with plural nouns to express the same gaseous quality across multiple items.
