säädöin

Säädöin is a Finnish term used in legal and administrative language to mean “by regulation” or “in accordance with regulations.” It derives from säädös, meaning regulation or decree, and the ending -in, a historical marker of means or by way of. The form is relatively formal and somewhat archaic in modern Finnish, and it is most commonly found in statutes, official guidelines, archival documents, and legal commentary. In everyday language, more common expressions are säädösten mukaan, lainsäädännön mukaan or asetusten mukaan.

In practice, säädöin functions as a marker of conformity to existing rules. It can appear in constructions such as säädöin vahvistetut ohjeet or säädöin ja määräyksin annettujen ohjeiden noudattaminen. The phrase is typically used together with other legal terms, and it is less common in contemporary everyday speech outside of formal or historical contexts.

Etymology and usage notes: säädös means regulation or decree, and -in is a suffix associated with means or instrument in formal Finnish phrasing. The combination yields a sense of action performed by means of, or in accordance with, regulations. Because of its formal tone, säädöin is often encountered in legal texts that seek to emphasize adherence to established rules rather than in casual prose.
