Välineittäin

Välineittäin is an adverb in Finnish that means by means of instruments or tools, i.e., instrument-wise. It is formed from väline, meaning instrument or tool, with the adverbial suffix -ittäin, which marks manner or distribution. The term is primarily used in scientific, technical, and analytical texts to indicate that results or observations are broken down according to the measurement instruments or devices used.

In practice, välineittäin is employed to distinguish data according to the equipment or method used for collection. For example: "Tulokset on esitetty välineittäin," meaning that the results are presented by instrument. "Mittaukset tehtiin välineittäin kolmella eri laitteella" indicates measurements were taken with three separate devices. The phrase can appear as "välineittäin mitattuna" or in similar constructions, though the standalone form välineittäin is common.

Usage context and style: Välineittäin appears most often in technical reports, experimental descriptions, and comparative studies where it is important to attribute findings to specific instruments or measurement methods. In everyday Finnish, the term is less common, but still understandable in appropriate technical contexts.

Related terms include laitekohtainen (device-specific), mittausmenetelmäkohtainen (by measurement method), and välineellinen (instrumental). The suffix -ittäin is a productive way to form adverbs describing distribution or manner, of which välineittäin is one specialized example.
