käynnistyvän

Käynnistyvään is the illative singular form of the present active participle käynnistyvä, derived from the Finnish verb käynnistyä (to start up, to come into operation). As a participial adjective, käynnistyvä describes something that starts or is in the process of starting, and it inflects like a normal Finnish adjective for number and case. The illative form käynnistyvään is used to indicate direction into a state associated with starting.

In practice, käynnistyvään commonly appears in phrases describing systems, machinery, or processes entering a startup state. For example: järjestelmä siirtyy käynnistyvään tilaan (the system shifts into a starting state) or käynnistyvään koneeseen (into a starting-up machine). The participle can also function in other cases: genitive singular käynnistyvän, partitive käynnistyvää, and so on, depending on the grammatical context. The base form, käynnistyvä, may be used as a plain attributive adjective: käynnistyvä järjestelmä (a system that is starting up).

The term is common in technical and everyday Finnish when discussing electronics, software, or processes that are booting up or becoming operational. It is related to nominal forms such as käynnistyminen (startup, booting) and käynnistys (start, initiation). See also käynnistys, käynnistyminen, sekä käynnistyä for related concepts.
