Sekundäärisiin

Sekundäärisiin is the illative plural form of the Finnish adjective sekundäärinen, used to refer to things that are secondary in relation to something primary. In Finnish, adjectives decline to match the noun they modify in number and case, and the illative plural form appears when the noun phrase is in the illative (into). Consequently, sekundäärisiin occurs most often in phrases such as sekundäärisiin kohteisiin or sekundäärisiin reaktioihin.

Origin and morphology: The adjective sekundäärinen is a loanword in Finnish, derived from Latin secundarius through intermediary European languages, with the modern form adapted to Finnish inflection. The illative plural form sekundäärisiin is produced according to standard Finnish rules for adjectives with plural nouns in the illative case.

Usage: Sekundäärisiin is primarily used in technical, scientific, or academic Finnish to distinguish secondary elements from primary ones. It is less common in everyday language, where speakers more often use terms like toissijainen or muu similar phrasing to convey a secondary status. The form tends to appear in formal writing, research reports, and theoretical discussions.

Examples: Tutkimus käsittelee sekundäärisiin kohteisiin liittyviä ilmiöitä. Sekundäärisiin reaktioihin liittyvät tekijät voivat vaikuttaa tuloksiin.
