Malmeista

Malmeista is a Finnish word form meaning “from the ores” or “of the ores,” and it is used in mining, geology, and related fields. It represents the elative plural form of malmi, which means ore. The root malm- combines with the plural suffix -e- and the elative case ending -sta (or -stä), to express origin or source when referring to multiple ore deposits or ore materials. Because Finnish morphology relies on case endings rather than prepositions, malmeista is typically found in contexts that describe provenance, composition, or derivation from ore resources.

In practice, malmeista appears in technical and scientific texts to mark sourcing or association with ore. For example, a report might refer to substances or metals as “malmeista peräisin olevat metalliseokset,” meaning metals derived from ore, or discuss samples described as characteristics tied to malmeista. The form is not a standalone noun but a grammatical case form, so it is used within larger noun phrases rather than as an independent term.

Etymologically, malmi (ore) provides the semantic core, while -sta attaches the meaning “from” and the -e- serves as a stem extension to integrate the plural elative ending. As a part of Finnish grammar, malmeista illustrates how origin and plurality are encoded directly in the word rather than through separate prepositions.
