Keemiliste

Keemiliste is the genitive plural form of the Estonian adjective keemiline, meaning chemical. It is used when the noun it modifies is in the genitive plural, and it often expresses relation, material, or type in a compound noun phrase such as “properties of chemical compounds” or “mechanisms of chemical reactions.” In Estonian, adjectives agree with the nouns they modify in number and case, so keemiline becomes keemiliste in the genitive plural.

Common uses include phrases like keemiliste ühendite omadused (properties of chemical compounds) and keemiliste reaktsioonide mehhanismid (mechanisms of chemical reactions). These constructions appear frequently in scientific, technical, and academic writing to specify that the referenced attributes or phenomena pertain to chemicals or chemical categories.

Keemiliste functions as a grammatical form rather than a standalone concept. It conveys that the associated noun refers to chemicals or chemical-related phenomena, while the noun itself appears in genitive plural (for example, ühendite, reaktsioonide, ainete). Learners should note the distinction between this genitive plural form and other adjective forms such as keemiline (singular nominative) or keemilised (plural nominative), which serve different grammatical purposes.

In short, keemiliste is the key inflected form used to describe plural chemical-related nouns in genitive phrases, reflecting Estonian’s system of adjective agreement and case marking.
