Keksinnöstään

Keksinnöstään is a Finnish grammatical form used to indicate origin or attribution to a person’s invention. It is formed from the noun keksintö (invention) combined with possessive and case endings, and is commonly translated as “from his/her invention” or “on the basis of his/her invention,” depending on the context.

In Finnish, the noun keksintö can take a possessive suffix to show ownership (for example, his/her invention) and, in conjunction with a case ending, can express source or origin. Keksinnöstään illustrates how possession and the ablative case interact in Finnish morphology: the form signals that a claim, idea, device, or feature is derived from or attributable to a particular inventor’s work. The exact translation may vary with the surrounding sentence and verb used.

Usage of keksinnöstään is typical in technical writing, patent discussions, biographical or historical texts, and analyses of innovation. It helps specify that a particular outcome, statement, or piece of technology stems from the inventor’s own creation. The construction reflects Finnish’s agglutinative nature, where multiple grammatical functions—such as possession and source—are expressed through suffixation on a base noun.
