kivettyjen

Kivettyjen is a Finnish grammatical form that appears as the genitive plural of the participial adjective kivettynyt, meaning petrified or calcified. As a genitive plural, kivettyjen is used to indicate possession or association with petrified things within noun phrases. It is most common in formal or technical Finnish, especially in fields where descriptions of petrified materials or fossilized remains occur.

In geology, paleontology and related disciplines, the concept of petrification or fossilization is central, and kivettyjen often enters discussions about petrified remains or calcified structures when describing what belongs to or concerns petrified items. In medical or dental contexts, similar phrasing can appear when referring to calcified tissues, deposits, or plaques, with the genitive plural signaling that the discussion concerns those petrified or hardened substances.

Etymology: the form derives from the verb kivettyä, meaning to become stone, through the participial stem kivettynyt/kivettyneet and the Finnish genitive plural ending -jen. The exact inflection (such as whether kivettyjen appears instead of kivetttyneiden in a given construction) depends on the noun being modified and the grammatical case required by the sentence.

Kivettyjen therefore functions as a grammatical inflection rather than a standalone lexical entry. It is a tool for precise, formal description in contexts dealing with petrified materials, fossilized remains, or calcified tissues. See also kivettyminen, fossiili, petrifikaatio.
