koneistonsa

Koneistonsa is a Finnish possessive form of the noun koneisto, meaning its mechanism, apparatus, or system of machinery. The phrase is used to refer to the mechanism belonging to a previously mentioned object or subject, for example in sentences describing how that mechanism functions or fails. It is common in technical and descriptive writing about equipment or devices.

The base noun koneisto refers to a mechanism or a coordinated set of components within a device, and can also be used figuratively for a complex internal system within an organization or process. The word forms part of Finnish scientific and engineering vocabulary and is suitable for precise, objective description.

Grammar and usage notes: koneistonsa is the third-person possessive form, built from koneisto plus the possessive suffix -nsä (with small orthographic variations such as -nsa depending on phonology). The form indicates ownership by a third party and is used without a separate possessive pronoun. In practice, koneistonsa often appears in noun phrases describing parts, conditions, or operations of a machine or system, such as koneistonsa voitelu (the lubrication of its mechanism) or koneistonsa vaurioituminen (wear of its mechanism).
