Öljyiltä

Öljyiltä is a Finnish noun form: the elative plural of öljy (oil). In Finnish grammar, the elative case expresses origin or source and is often translated as “from” or “out of” in English. Therefore öljyiltä literally means “from the oils” or “out of the oils,” referring to multiple oil sources or oil-based substances.

The elatiive plural is used when describing something that originates from more than one oil or from oil-derived material. It is common in technical, environmental, and industrial contexts, where the origin of a substance, contaminant, or product must be specified. The form is typically combined with a noun in the elative-derived construction, for example: öljyiltä peräisin oleva epäpuhtaus, meaning “an impurity originating from oils.”

Usage notes: öljyiltä peräisin oleva is a standard way to describe origin in compound noun phrases. In everyday speech, you might instead hear more general expressions, but in scientific and regulatory language the elative plural öljyiltä is well established. As with other Finnish inflected forms, the meaning of öljyiltä depends on the head noun it modifies.

Etymology: the word combines the root öljy with the elative plural suffix -iltä, following regular Finnish noun inflection. Translation into English varies by context and could be “from the oils,” “oil-derived,” or “originating from oils.”
