liittyneistä

Liittyneistä is a Finnish inflected form derived from the participle liitetty or, more commonly in this context, liittynyt, meaning joined or related. It is used to refer to a group of things or people that are connected to a previously mentioned topic. In Finnish, forms like liittyneistä appear when the referent is plural and the sentence requires a specific case, typically the elative (from/among) or a related case in a predicative or modifier position.

In practice, liittyneistä appears in phrases that discuss material related to another subject. For example, liittyneistä asioista means “about the related matters,” and liittyneistä henkilöistä means “about the related persons.” The form helps to link information to a set of items that are connected to the main topic, without repeating the noun each time.

Grammatical note: liittyneistä is one of several inflected forms of the participle related to liityä. Other forms include liittyneet (nominative plural, “the related ones”) and liittyneen or liittyneestä (singular forms for genitive or elative). The choice of form depends on number and the syntactic role in the sentence. Finnish speakers use this morphology to create concise, referential phrases when enumerating or discussing related elements.

Summary: liittyneistä is a plural, case-marked form of a related/connected participle used to indicate items connected to a prior topic. It is common in written Finnish, especially in analytic, technical, or explanatory prose where related topics or entities are being described.
