reiityksiin

Reiityksiin is a Finnish illative plural form of the noun reiitys, which means perforation or perforated section. In technical and industrial Finnish, reiityksiin is used to refer to the perforation-related aspects of a material, component, or process, particularly when discussing multiple perforations or perforated regions. The term is common in texts about packaging, textiles, and paper production where perforations are designed or controlled as part of the product design or manufacturing method.

Usage examples include references to perforation lines in packaging that enable tearing, or to perforated patterns in paper and textile materials. In quality control and standards documentation, reiityksiin may appear in phrases describing requirements for perforated features across production lots or product lines. Because it is a grammatical form, reiityksiin appears primarily in written Finnish rather than spoken language.

Etymology and grammar: reiityksiin is formed from the base noun reiitys (perforation) with the illative plural suffix -iin, yielding roughly "into perforations" or "to perforations." The form is used when the illative case is required to indicate direction toward perforations or to discuss perforations as a concept rather than as a concrete object. Related terms include reiitys and other perforation-related vocabulary.
