Kivilajiksi

Kivilajiksi is the translative form of the Finnish noun kivilaji, meaning rock type. It is used to express becoming or being classified as a rock type. In geology and petrology, kivilajit are the categories of rocks by origin and composition, such as igneous, sedimentary, and metamorphic types. The translative ending -ksi (here in the singular form kivilajiksi) marks a change of state or a designation, indicating that something is identified or transformed into a particular rock type.

In practice, kivilajiksi is used in sentences that describe classification or transformation. Examples include: Näyte luokitellaan kivilajiksi (The sample is classified as a rock type). Tämä kivilajiksi määrittely auttaa ymmärtämään kiven koostumusta. (This designation as a rock type helps to understand the composition of the stone.) The form can also appear in descriptions of metamorphic or diagnostic processes where something becomes or is treated as a specific rock type.

Usage notes: kivilajiksi is a grammatical form rather than a distinct geological category. The related terms are kivilaji (rock type) and kivilajit (rock types). It is common in scientific Finnish to pair kivilajiksi with verbs such as luokitella, määritellä, or muuttaa, to express classification, definition, or transformation.
