Historiallisista

Historiallisista is a Finnish adjective form that functions as the elatiivi (elative case) plural form of the base adjective historiallinen. It is used to describe plural nouns in contexts where the phrase indicates origin or source from the historical, such as from historical sources, works, or events. Because it is an inflected form, historiallisista does not stand alone as a noun; it modifies a following plural noun in sentences.

In practice, historiallisista appears most often in academic and historical writing when referring to material or information derived from the past. It typically accompanies plural nouns in the elatiivi case, for example historiallisista lähteistä (from historical sources) or historiallisista tapahtumista (from historical events). Related forms include historiallisten (genitive plural), historiallisia (partitive plural), and historiallisissa (inessive plural), reflecting the broader system of Finnish adjective declension across cases and numbers.

Usage notes:

- The form signals that the associated noun relates to the past or to history, and that the reference is through sources or examples from that period.

- It commonly occurs in phrases describing evidence, documentation, or scholarly discussion grounded in historical material.

Examples:

- Tutkimus nojaa historiallisista lähteistä saatuihin tietoihin. (The study relies on information obtained from historical sources.)

- Historiallisista tapahtumista kertovat teokset tarjoavat kontekstia aikakaudiin. (Works that describe historical events provide context for the era.)
