yttersta

Yttersta is a Swedish adjective meaning outermost, farthest outward, or most external. It is used to describe position, extent, or degree in space, time, or abstraction. The form is a superlative, derived from the stem ytter/yttre with the suffix -sta, and it is typically placed before a noun or used with a definite form: det yttersta lagret (the outermost layer), den yttersta kanten (the outermost edge).

In practice, yttersta is common in geology, geography, astronomy, and related fields to denote the furthest outward layer or boundary. In everyday language it can describe the outermost part of an object, the edge of a region, or the final stage of a process: den yttersta delen av jorden, den yttersta fasen av utvecklingen.

Yttersta can also be used metaphorically to indicate ultimate limits or extremes: yttersta gränsen för vad vi tolererar (the outermost limit of what we tolerate). The term supports both literal and figurative expressions, making it a versatile descriptor in Swedish.

Cognates exist in other Scandinavian languages, where similar forms mean outermost. In Norwegian and Danish, corresponding terms such as ytterste carry related meanings, reflecting shared Germanic roots.
