kiihtynyt

Kiihtynyt is a Finnish adjective and the perfect passive participle of the verb kiihtyä, meaning to accelerate, to increase, or to become excited. It describes a state that has become more rapid or intense and can modify nouns or function predicatively with the verb olla.

Etymology: The form derives from the verb kiihtyä, with the participle suffix -nyt marking the perfect passive participle. Related forms include kiihtyminen (acceleration, escalation) and kiihtynyt used as an adjective. A contrasting present participle is kiihtyvä (accelerating).

Usage: In neutral or technical language it often refers to physical quantities or processes, such as temperature, speed, or growth. In everyday usage it can describe more abstract developments, like demand or interest. The phrase typically appears with olla in a compound tense: lämpötila on kiihtynyt; kysyntä on kiihtynyt; tilanne on kiihtynyt.

Examples: Lämpötila on kiihtynyt viimeisten tuntien aikana. Kysyntä on kiihtynyt nopeasti. Tilanne on kiihtynyt äkillisesti.

Note: Kiihtynyt frequently conveys a measurable or noticeable increase; it is more specific than general terms for growth and should be distinguished from synonyms that simply indicate gradual growth.
