Gaasiliste

Gaasiliste is an Estonian grammatical form used to describe objects or phenomena in the gas phase. It is the plural genitive form of the adjective gaasiline, meaning gaseous or gas-like. As a word form, gaasiliste does not denote a separate scientific concept; its role is to modify a noun in phrases that refer to gaseous states or properties.

Examples include gaasiliste ainete omadused (properties of gaseous substances) and gaasiliste ühendite reaktsioonid (reactions of gaseous compounds). In such phrases, gaasiliste indicates that the described substances or compounds are in the gaseous state.

Etymology: gaasiline is derived from gaas (gas) plus the suffix -iline; gaasiliste is formed via the standard Estonian plural genitive ending for adjectives.

Notes: The term is not a defined scientific category. It is a grammatical form commonly found in Estonian-language scientific writing and textbooks. Non-native speakers may encounter it as part of noun phrases rather than as a distinct concept.
