partikkeliin

Partikkeliin is the illative form of the Finnish noun partikkeli, meaning “into a particle” or “to a particle.” In Finnish linguistics, partikkeli denotes a part of speech whose members are used to express mood, attitude, or discourse function rather than referential content. Finnish partikkelit include, for example, question particles such as -ko/-kö and other particles that color a statement or regulate the discourse.

The illative case marks direction toward something or movement into a location, and partikkeliin is formed when the noun partikkeli takes the illative suffix. The use of partikkeliin is limited to grammatical discussion and writing that requires explicit reference to the form itself; it is not a common everyday construction. In ordinary texts, one would more often encounter illative forms with concrete nouns indicating places, such as taloon (to the house) or kaupunkiin (into the city).

For learners, partikkeliin serves as an example of how Finnish inflection changes the end of a noun to express direction, and it sits within the broader system of case endings that governs illative usage in the language. The concept is primarily of interest in language study and reference materials, rather than as a frequently used everyday form.
