Cylindriska

Cylindriska is a term primarily found in Swedish-language scientific and descriptive writing, used to indicate a cylindrical, tube-like shape. The form derives from the Latin cylindrus, via the Greek kylindros, and corresponds to the English adjective cylindrical. In modern Scandinavian usage, cylindriska functions as the plural or feminine plural form of the adjective used with nouns describing cylindrical objects or forms.

In practice, cylindriska describes any object whose main geometry resembles a cylinder. In biology, the term may appear in phrases such as cylindriska bakterier or cylindriska celler to denote rod-shaped or tube-like morphologies, though more common taxonomic terms such as baciller are also used. In geology and crystallography, cylindriska kanter or cylindriska kristaller describe minerals or crystals that exhibit a cylindrical habit or elongated, round cross-sections. In engineering and architecture, cylindriska komponenter or cylindriska rör refer to cylindrical components, pipes, or structural elements.

The concept is primarily descriptive, helping to convey form without committing to a particular material, function, or taxonomic category. While cylindriska is most typical in Swedish sources, related terms exist in other Scandinavian languages with parallel meanings.
