mittariin

Mittariin is the illative case form of the Finnish noun mittari, meaning a meter, gauge, or measuring instrument. In Finnish grammar, the illative form is used to express movement toward or insertion into something, or the destination of an action. Therefore mittariin signals “into the meter” or “to the meter” and is common in technical and lab contexts where data are entered into a device or where one moves toward a measuring instrument.

In practical use, mittariin appears in sentences that describe interacting with measuring devices or entering values into them. For example: Aseta uusi arvo mittariin (Set a new value into the meter). Syötä tulokset mittariin (Enter the results into the meter). Kalibroi laite syöttämällä kalibrointiarvo mittariin (Calibrate the device by entering the calibration value into the meter). The word can also be used in broader phrases to indicate direction toward multiple devices, such as mittareihin for the plural illative (to the meters).

Etymology and form: mittari is derived from the stem mitta, meaning measurement, with the instrument-form suffix -ari. The illative suffix -in or -iin attaches to form mittariin in the singular. The corresponding plural illative is mittareihin.

Related forms include other cases of mittari (mittarin in genitive, mittarille for allative, etc.), and the plural mittarit as the nominative plural. Mittariin thus functions as a specialized grammatical form used chiefly in technical Finnish to specify action directed toward a measuring instrument.
