Toistettaviin

Toistettaviin is a Finnish grammatical form functioning as the illative plural of the participial adjective toistettava, which means “to be repeated” or “repeatable.” In usage, it describes nouns that are intended to be repeated, and it commonly occurs in formal or technical language. The form joins the participial stem with the illative plural suffix -iin, so it typically precedes a noun in illative plural (into…).

Morphologically, toistettaviin is built from the stem toistettav- plus the illative plural ending -iin. It is the illative-case, plural-inflected version of the adjective/participle toistettava. As such, it agrees with the noun it modifies in case and number, yielding phrases like toistettaviin tehtäviin or toistettaviin kokeisiin to express “tasks to be repeated” or “experiments to be repeated.”

Usage and meaning are centered on repetition requirements. The phrase is used to specify items or tasks that must be repeated, rechecked, or re-tested, often in procedural, methodological, or instructional contexts. It conveys a sense of obligation or plan for repetition rather than a general property of the noun.

Examples include:

- toistettaviin tehtäviin liittyvät ohjeet (instructions related to tasks to be repeated)

- toistettaviin kokeisiin valmistautuminen (preparation for experiments to be repeated)
