käsittelyyn

Käsittelyyn is the illative case form of the Finnish noun käsittely, which broadly means handling, processing, or treatment. The illative form signals direction toward processing or the purpose of processing, as in phrases meaning “for processing” or “into processing.” The term is common in contexts where data, materials, or procedures are to be processed or handled.

Finnish nouns change form to reflect grammatical cases. Käsittely is a deverbal noun derived from the verb käsitellä (to handle, to process). The illative suffix (-yn) indicates movement toward or target of action. Therefore käsittelyyn can be paired with verbs or adjectives that require an illative complement, for example “tietojen käsittelyyn” (for data processing) or “käsittelyyn liittyvät ohjeet” (instructions related to processing).

Common usage: in data protection, computer science, logistics, and material processing, where it denotes the phase or scope of processing before action is taken. It also appears in legal and administrative language to specify what must be processed or handled. Examples: “Tietojen käsittelyyn käytettävät ohjelmistot” (software used for data processing), “Aineiston käsittelyyn tarvitaan lupia” (permits are required for processing of the material).

Note: käsittelyyn should not be confused with other case forms of käsittely, such as the nominative käsittely or the partitive käsittelyä. In Finnish, the illative form marks direction toward or purpose related to processing, and its exact form may vary with the stem due to vowel harmony and consonant gradation.
