Kiteytyvän

Kiteytyvän is the genitive singular form of the present active participle kiteytyvä in Finnish. The present active participle describes an ongoing action and functions as an adjective, so kiteytyvän is used to modify a noun and agrees with it in case, number, and definiteness. The form arises from the verb kiteytyä, meaning to crystallize or to form crystals.

In usage, kiteytyvän commonly appears in scientific and technical Finnish to describe processes, substances, or phenomena related to crystallization. It can be placed attributively before a noun, and its genitive singular form allows phrases such as kiteytyvän aineen koostumus (“the composition of the crystallizing substance”) or kiteytyvän prosessin nopeus (“the rate of the crystallizing process”). The form also participates in broader morphological patterns where adjectives derived from verbs take on case endings.

Etymology and related terms: kiteytyvän derives from the verb kiteytyä, with the root kiteyty-, and is related to the noun kide (crystal). Related forms include kiteytyvä (the present active participle in nominative form) and kiteytyminen (crystallization). The word is chiefly encountered in technical contexts but also appears in descriptive Finnish outside specialized writing to convey ongoing crystallization as a characteristic of a process or substance.
