höyryiden

Höyryiden is the genitive plural form of the Finnish noun höyry, meaning steam or vapor. It is used to indicate possession or association with multiple steams or vapors, particularly in technical, scientific, and descriptive writing. For example, höyryiden koostumus means the composition of vapors, and höyryiden paine refers to the pressure of a vapor or vapor mixture.

The word höyry is a native Finnish noun, and the genitive plural suffix -iden is added to form höyryiden. This form is commonly found in contexts that discuss gas mixtures, thermodynamics, meteorology, and industrial processes where vapors are described as a group rather than as a single steam.

In everyday Finnish, speakers typically use höyryt to refer to steam in general, or other case forms such as höyrystä for partitive. Höyryiden appears mainly in written language and is especially prevalent in technical or formal prose when the vapors themselves are being discussed as a collective entity or possessive reference.
