Elastickou

Elastickou is a Czech word-form of the adjective elastický, meaning elastic. It is used to describe feminine singular nouns in certain grammatical cases, most commonly the accusative and instrumental, and it appears with nouns such as past a feminine noun in those cases (for example, elastickou látkou or elastickou páskou).

Etymology and meaning: The adjective elastický derives from the Greek elastikos, through Latin elasticus, and shares the same semantic core as the English word elastic. The form elastickou reflects Czech morphology for feminine singular in the accusative or instrumental cases.

Usage and examples: In Czech, adjectives decline to agree with the gender, number, and case of the noun they modify. Elastickou appears before a feminine singular noun in the accusative or instrumental case. Examples include elastickou pásku (elastic tape) in the accusative and elastickou látkou (with elastic fabric) in the instrumental. The form cannot be used for masculine, neuter, or plural nouns; different endings are used for those genders and numbers (elastický for masculine singular nominative, elastická for feminine nominative, elastické for neuter singular or plural, etc.).

See also: The word is part of the Czech adjective system and relates to similar forms in other Slavic languages, where corresponding adjectives convey the meaning of stretchiness or resilience in materials, bodies, and phenomena described as elastic.
