Ajanjaksoittain

Ajanjaksoittain is a Finnish adverbial expression used to designate that information is organized, analyzed, or presented according to time periods. The form is built from ajanjakso, meaning a time period or era, combined with the suffix -ittain, which indicates a division or manner of presentation (by, according to). In practice, ajanjaksoittain signals a chronological or period-based segmentation rather than a topic-based or thematic arrangement.

Usage and function

Ajanjaksoittain is commonly employed in academic writing, historiography, statistics, and museum or archival contexts. It describes how material is grouped into consecutive time intervals—such as decades, centuries, or era-based blocks—and how findings or descriptions proceed from one period to the next. It can accompany descriptions of data, events, or developments to emphasize temporal order.

Example sentences

The report presents population changes ajanjaksoittain, from 1950–1960, 1960–1970, and so on. The exhibit arranges artifacts ajanjaksoittain, highlighting stylistic transitions across successive periods.

Relation to similar concepts

Ajanjaksoittain is closely related to the idea of chronological or period-based organization. It is distinct from a simple thematic arrangement, as it foregrounds time as the governing structure. Related Finnish terms include kronologinen järjestys (chronological order) and aikajakso (time period).

Notes
