rekisteröidyistä

Rekisteröidyistä is a Finnish grammatical form used to refer to people who have completed the action of registering themselves. It is derived from the verb rekisteröityä (to register oneself) and is commonly found in formal language, such as administrative documents, research reports, and policy texts. The form signals a subset of a population defined by having registered.

In use, rekisteröidyistä describes a group in relation to another noun or in a context that specifies origin or composition. It often appears in phrases like rekisteröidyistä henkilöistä or rekisteröidyistä käyttäjistä, meaning “of the registered people” or “from among those who have registered.” The form is not typically used as a stand-alone noun; it functions as a participial modifier that aligns with the case and number of the noun it describes.

Grammar note: rekisteröidyistä is a plural participial inflection and is encountered in dependent clauses or noun phrases where the referent is defined by registration. Its exact case form depends on the surrounding syntactic structure, just as with other Finnish participial adjectives. Because Finnish grammar uses numerous case endings, the appearance of rekisteröidyistä can vary depending on what case the overall phrase requires.

Examples (Finnish with rough translations):

- Tiedot on kerätty rekisteröidyistä käyttäjistä. (The data were collected from the registered users.)

- Rekisteröidyistä vastaajista saatiin tilastollisesti merkitseviä tuloksia. (From among the registered respondents, statistically significant results were obtained.)
