turbiniin

Turbiniin is a grammatical form in Finnish, not a separate English word. It is the illative singular form of turbiini, meaning turbine. The illative indicates motion toward or into a location or object and is commonly used with verbs of movement or direction. Therefore, turbiniin is used when the turbine is the destination of an action, for example when directing a substance into the turbine or describing movement toward it.

In practice, turbiniin appears in technical and engineering contexts where precise directions matter. The base noun turbiini refers to a turbine, a device that converts fluid or gas flow into mechanical energy, often part of power plants, aircraft engines, and industrial machines. When forming sentences, the illative ending attaches to the noun stem, yielding turbiniin, while other cases express different relationships to the turbine (for example, turbii-nissa for “in the turbine”).

Examples:

- Öljy johdettiin turbiniin testauksen vuoksi. (Oil was directed into the turbine for testing.)

- Polttoaine ruiskutettiin turbiniin säätöjen tarkistamiseksi.

Related forms include turbiiniin with variants for other cases, such as turbiinissa (in the turbine) and turbiinin (genitive form). As a grammatical form, turbiniin functions to convey direction toward the turbine rather than representing a standalone lexical item.
