Viskösa

Viskösa is a Swedish adjective meaning viscous. It describes liquids and semi-solid materials that resist flow due to internal friction. The base form is viskos, with viskös used for singular common-gender nouns and viskösa used for plural common-gender nouns (for example, viskösa vätskor = viscous liquids). The neuter singular form is visköst. The term is closely related to viscosity (viskositet) and is common in physics, chemistry, and materials science, as well as in everyday language when precision is preferred.

Origin and grammar: Viskösa derives from the Latin viscosus, transmitted into Swedish through European linguistic development. The adjective follows ordinary Swedish declension patterns, with different endings for singular and plural forms and for gendered noun classes.

Usage: In technical writing viskösa is used to describe substances with high resistance to flow, such as honey, molasses, syrups, tar, polymer melts, and many gels. In everyday speech, speakers may use less precise terms like tjock or klibbig, but viskos is the precise descriptor in scientific and descriptive contexts.

Examples: Sirapen är viskös. De viskösa vätskorna flyter långsamt. Viskositeten ökar när temperaturen sjunker.
