Periaatteidensa

Periaatteidensa is a Finnish noun form meaning “their principles.” It is the third-person plural possessive construction attached to the plural noun periaatteet (principles). In Finnish, possessive suffixes combine with nouns to indicate ownership by a group or multiple holders, and periaatteidensa is used when referring to the principles of a plural subject.

The form is most often encountered in phrases such as periaatteidensa mukaan, meaning “according to their principles,” or periaatteidensa mukaisesti, meaning “in accordance with their principles.” These expressions appear in political, ethical, corporate, and organizational discourse to attribute actions, stances, or policies to a group by reference to its stated principles.

Morphology and usage notes: periaatteidensa is built from periaateet (principles) with the third-person plural possessive suffix -idensa. The suffix signals possession by a plural subject (they). The phrase functions within compound expressions to connect agency with guiding beliefs, and the exact reference (which group’s principles) is determined by context.

Examples:

- Yhtiö on toiminut periaatteidensa mukaan. (The company has acted according to its principles.)

- Keskusteluissa on korostettu periaatteidensa mukaan toimimisen tärkeyttä. (In discussions, the importance of acting according to its principles has been emphasized.)
