varsinaisiin

Varsinaisiin is the illative plural form of the Finnish adjective varsinaiset, meaning real, genuine, or proper. In Finnish, the illative case marks movement into or toward something, so varsinaisiin is used when the governed noun is in illative plural. As an adjective, varsinaiset agrees with the noun in number and case, for example in phrases such as varsinaisiin tiloihin (into the real rooms) or varsinaisiin tarkoituksiin (for real purposes).

Grammatically, varsinaisen stem is varsinais-, with required inflection to illative plural as varsinaisiin. Other common forms of the same adjective include nominative plural varsinaiset, genitive plural varsinaisten, and partitive plural varsinaisia. These forms allow the word to function across the full spectrum of Finnish adjective inflection while preserving the nuance of authenticity or seriousness associated with “real” or “proper.”

Usage notes: varsinaisiin is typically found in written or formal Finnish, especially in analytical, argumentative, or technical contexts where the distinction between genuine or main aspects and surface or assumed ones is important. It often emphasizes quality, substance, or intention rather than appearance.
