höyryistä

Höyryistä is the elative plural form of the Finnish noun höyry, meaning steam or vapor. The elative case expresses origin or source, so höyryistä can be translated as “from the steam” or “from steams” depending on the context. The form is used when referring to more than one steam source or when describing steam as a material or energy source.

In Finnish, höyry is a regular noun with the following typical forms: nominative plural höyryt, genitive plural höyryjen, and elative plural höyryistä. Thus höyryistä indicates origin or extraction from steam in plural contexts. The form is common in technical, scientific, and industrial descriptions, as well as in descriptions of processes involving steam and condensation.

Usage notes include that höyryistä tends to appear in contexts discussing sources of vapor, condensation processes, or energy transfer where multiple steam sources are involved. It is not a casual everyday term, but rather a standard grammatical form used in formal and descriptive Finnish.

Examples:

- Kondensaatiopilvi muodostuu höyryistä. (A condensation cloud forms from steam.)

- Neste on peräisin höyryistä. (The liquid is derived from steam.)
