reiitettyjen

Reiitettyjen is a Finnish grammatical form that functions as the genitive plural of the adjective or past participle reiitetty, meaning perforated. The form is used to denote possession or association with a noun in genitive plural, typically in phrases describing perforated items as a group. In practice, reiitettyjen appears in technical, manufacturing, or product-description contexts.

The base verb is reiittää, meaning to perforate, with the related noun rei'itys meaning perforation. Reiitetty describes something that has been perforated, and reiitettyjen modifies a following noun in the genitive plural (for example, levyjen). This aligns with Finnish adjective agreement rules, as seen in examples such as vihreiden talojen, where the genitive plural forms of adjective and noun agree to indicate a possessive or qualitative relationship.

Common usage can be found in phrases like reiitettyjen levyjen tuotanto (production of perforated sheets), reiitettyjen kappaleiden lukumäärä (the number of perforated pieces), or reiitettyjen tuotteiden laatu (the quality of perforated products). The form is primarily found in written, technical language and is rarely interpreted as a standalone noun; it functions within noun phrases to specify characteristics of a set of items.
