oikeaistu

Oikeaistu is a Finnish term that appears mainly in informal speech and writing. It is not a standard dictionary entry, but is typically understood as a compound of oikea meaning "right" and istu or istuin related to sitting or seats. Because it is not widely regulated by authorities, its exact meaning can vary with context.

Most commonly, oikeaistu is interpreted as referring to "the right-hand seat" in a seating arrangement. In practical terms, this can mean the seat on the right side of a vehicle or the right-hand position in a row or chamber, measured from an agreed reference point such as the driver’s seat. In Finland, where cars are driven on the right and the driver sits on the left, the oikeaistu would usually correspond to the front passenger seat.

Beyond physical seating, the term can be used more loosely to indicate a position or place on the right side within a lineup, arrangement, or discussion, though such usage remains informal and context-dependent.

Because oikeaistu is not part of formal Finnish vocabulary, its usage tends to be limited to casual contexts, slang, or descriptive phrasing. Speakers who encounter or adopt the term should consider their audience and the potential for ambiguity, especially in formal writing.
