Jaksoisista

Jaksoisista is a Finnish word-formation that can be analyzed as an elative plural form built from a stem related to the word jakso, meaning period or episode. In practice, jaksoisista most often functions as the elative plural of an adjective stem jaksois-, derived from the adjective jaksoinen, which can be translated roughly as “periodic” or “episodic.” The exact meaning of jaksoisista depends on the surrounding noun and the context in which it occurs.

In Finnish grammar, the ending -ista (or -istä after back vowels) marks the elative case in the plural, indicating movement or relation from something. When attached to the stem jaksois-, the result jaksoisista can appear in phrases such as jaksoisista tapahtumista, meaning “from the periodic events” or “from the episodic events.” This form is therefore primarily a grammatical inflection rather than a standalone lexical item with a fixed translation.

Usage of jaksoisista is relatively limited to contexts where the speaker intends to refer to things in a periodic or episodic sense, such as technical, literary, or analytical prose. It is not a common everyday term, and its presence typically signals a discussion of time, sequences, or recurring phenomena.

Etymology and related forms: jakso– (period, episode) + -inen (adjectival suffix) to form jaksoinen (periodic/episodic). The elative plural suffix -ista/-istä yields jaksoisista as the form suitable for “from the periodic/episodic [things]” in relevant phrases.
