Ripuliin

Ripuliin is a Finnish linguistic term describing a particular inflected form of the noun ripuli, which means diarrhea. It is the illative singular form, used to express movement into the state designated by the noun. In Finnish, the illative case marks direction into something or into a state of being. The construction ripuliin thus signals “into diarrhea” or “into a state of diarrhea.” The form is primarily of interest to students of Finnish grammar, lexicographers, and linguists, rather than a common word used in everyday speech.

Etymology and morphology: Ripuli is a native Finnish noun; the illative suffix attaches to the stem to form ripuliin. The word illustrates how Finnish inflection attaches case endings to convey nuance of direction and state.

Usage notes: Because the combination of a bodily state with illative is unusual in everyday language, ripuliin is rarely used outside linguistic examples, dictionaries, or academic discussions. It may appear in grammatical explanations or as part of example sentences demonstrating the illative case.
