Yleisiin

yleisiin is the illative plural form of the Finnish adjective yleinen, meaning general or common. It is used when the noun it modifies is plural and in the illative case, often to indicate movement toward or focus on generalities rather than specific items. Common contexts include phrases such as yleisiin aiheisiin, yleisiin kysymyksiin or yleisiin teorioihin, which translate roughly to “to general topics,” “to general questions,” and “to general theories.”

In Finnish, adjectives agree with the nouns they modify in number and case. Therefore yleinen can take multiple inflected forms, including illative singular (yleiseen) and illative plural (yleisiin). The illative plural yleisiin marks a reference to a broad or non-specific set of items within a plural noun phrase, for example yleisiin kysymyksiin (to general questions) or yleisiin aiheisiin (to general topics).

Usage and nuance: yleisiin is predominantly a descriptive, general-purpose form used in formal or academic writing. It signals that the discussion concerns broad principles, common cases, or generalities rather than particular instances. While common in written Finnish, its use in everyday speech is less frequent and often observable in collocations such as yleisiin kysymyksiin liittyvät teemat or yleisiin teorioihin viittaavat esimerkit.

In sum, yleisiin is a grammatical inflection rather than a standalone word, serving to express a general, non-specific scope when discussing plural nouns in the illative case.
