aikaväleiltä

Aikaväleiltä is the elative plural form of aikaväli, a Finnish noun meaning a time interval. In Finnish grammar, elative marks origin or source, so aikaväleiltä translates roughly to “from time intervals” or “out of the time intervals.” The form is used when referring to multiple intervals as the source of data, observations, or events.

Etymology and grammar: The noun aikaväli combines aika (time) and väli (gap, interval). The suffix -ltä (elative) signals origin, and its plural form aikaväleiltä is used when the source consists of several intervals. This form is common in technical and scholarly writing that discusses data collected across different periods.

Usage: Aikaväleiltä is typically used to describe something drawn from several time intervals. It often appears in research reports, data analyses, historical summaries, and similar contexts where the source of information spans more than one period. Examples include data collection, sampling, or observations that originate from multiple periods.

Examples:

- Havaintoja kerättiin aikaväleiltä 2010–2015 ja 2016–2020.

- Aineistoa analysoitiin vahvistamalla havaintoja aikaväleiltä, joihin kerätty data kuului.

- Tulokset perustelevat trendin, joka on peräisin aikaväleiltä useista eri ajanjaksoista.

Related terms and notes: The singular counterpart is aikaväli (time interval). Other grammatical forms of the term include aikaväliin (illative, into a time interval), aikavälistä (elative singular, from a time interval). The concept is primarily used in technical Finnish, such as statistics, data science, and historical analysis.
