Keemilisi

Keemilisi is the partitive plural form of the Estonian adjective keemiline, meaning chemical. In Estonian, adjectives inflect for number and case to agree with the nouns they modify. The form keemilisi appears before plural nouns in the partitive case, signaling indefiniteness, partial quantity, or emphasis on the substance rather than a countable set of items.

Usage and examples. Keemilisi aineid translates to chemical substances, and keemilisi reaktsioone translates to chemical reactions in the partitive plural. The corresponding nominative plural is keemilised, as in keemilised ained (chemical substances) or keemilised reaktsioonid (chemical reactions). Partitive forms like keemilisi are common in contexts such as negation, expressions of quantity, or when the action affects an indefinite amount of material.

Origin and grammar. Keemiline derives from keemia (chemistry), a term borrowed from German Chemie and related to the broader word family for chemistry and chemical substances. The partitive plural form keemilisi is one of several inflected forms used by Estonian adjectives to match the case and number of the noun they describe.
