säännönmukaisten

Säännönmukaisten is a Finnish grammatical form used as the genitive plural of the adjective säännönmukainen, which means 'regular, rule-based, or conventional.' As an attributive adjective, säännönmukaisten describes a head noun that is in the genitive plural. In practice this means the phrase is used to indicate that the described things follow established rules or procedures, and it appears in contexts where a noun such as toimintatapa, käytäntö, or periaate is in the genitive plural.

In usage, säännönmukaisten is often part of a larger noun phrase within a sentence, usually preceding a head noun that is itself in genitive. For example, säännönmukaisten toimintatapojen noudattaminen means 'the adherence to the regular procedures,' and säännönmukaisten periaatteiden tulkinta means 'the interpretation of the rule-based principles.' The form contrasts with säännönmukaiset, the nominative plural meaning 'the regular ones,' which would serve as the subject of a clause rather than as part of a genitive phrase.

Etymologically, the adjective combines sääntö (rule) with -mukainen (like, resembling, or based on), creating a term that emphasizes adherence to established rules. Säännönmukaisten is common in formal, administrative, legal, and scientific Finnish when describing practices, protocols, or phenomena that are governed by rules.

Related terms include säännönmukainen (singular), säännönmukaisuus (regularity or conformity to rules), and synonyms such as tavanomainen or normatiivinen, depending on nuance.
