rekisteröidyssä

Rekisteröidyssä is a Finnish grammatical form derived from the verb rekisteröityä, meaning to register oneself. It represents the inessive form, indicating a location or state—in this case a state of being registered. The form is most commonly found in formal or administrative language, where precise descriptions of status in a registry, service, or database are required.

In usage, rekisteröidyssä is used to describe something that exists in or is part of a registered state or system. It appears in phrases that specify where or how something is registered, such as in registries, databases, or official documents. Because it is a specialized inflection, it is encountered mainly in bureaucratic text, legal language, or technical descriptions rather than everyday speech.

Examples, though somewhat technical, illustrate the idea: rekisteröidyssä järjestelmässä oleva käyttäjä (a user in a registered system); tieto rekisteröidyssä tilassa (information in the registered state). The exact wording can vary depending on the surrounding grammar, but the core meaning remains: the subject is associated with being registered.

Relation to other forms: rekisteröidyssä is linked to the verb rekisteröityä (to register oneself) and to rekisteröinti (registration) as part of the same word family. It is the inessive-case inflection, formed with the -ssa/-ssä suffix, and contrasts with forms used for non-registered or future-registration contexts, such as imperatives or other cases.
