Tuolissa

Tuolissa is a Finnish word form that translates roughly as “in the chair.” It is the inessive case of the noun tuoli (chair) and is used to indicate location inside or within a chair, or more commonly, that someone or something is seated in a chair.

In Finnish, case forms convey spatial relationships rather than using prepositions. The inessive suffix -ssa/-ssä attaches to the noun to express “in” or “inside.” For example, the sentence Hän istuu tuolissa means “He sits in the chair,” and Kissa on tuolissa means “The cat is in the chair.” The form is also used to talk about objects being placed inside the chair’s space, though practical usage often centers on people or animals seated in a chair.

The plural form is tuoleissa, used when referring to multiple chairs, as in Keksejä on tuoleissa or more commonly in contexts describing several people seated in different chairs. The related adessive form tuolilla means “on the chair” (on top of or at the chair’s surface), illustrating how Finnish relies on distinct cases to express subtle spatial distinctions.

Tuolissa is a standard, widely understood element of Finnish grammar and does not denote a separate concept or proper noun. Its primary relevance is in illustrating how location and posture are encoded morphologically in Finnish. See also tuoli (chair) and the inessive case in Finnish grammar.
