sammuttavan

Sammuttavan is a Finnish grammatical form derived from the verb sammuttaa, meaning to extinguish or to switch off. It is the genitive singular form of the present active participle sammuttava. In Finnish, present active participles function as adjectives or as noun-like modifiers, and their endings change to agree with the noun they describe. Therefore sammuttavan is used when the participle modifies a noun in a way that requires a genitive connection, for example in phrases like the extinguishing device’s or the extinguishing action’s.

As a present active participle, sammuttava describes someone or something that extinguishes or is capable of extinguishing. The form sammuttavan specifically marks possession or relationship to another noun, functioning much like an attributive adjective in compound noun phrases. This usage is common in technical, safety, and formal language where the action of extinguishing is referenced or qualified.

Usage and examples:

- Sammuttavan laitteen toiminta on suunniteltu nopeasti reagoivaksi. (The extinguishing device’s operation is designed to respond quickly.)

- Sillä on optio sammuttavan toiminnon automatisoinnista. (It includes an option for automating the extinguishing action.)

- Sammuttavan järjestelmän valinta riippuu tilan koosta ja riskitasosta. (The choice of the extinguishing system depends on room size and risk level.)

Related terms include sammuttaa (to extinguish), Sammutus (extinguishing or firefighting as a process), and sammuttava (the present active participle in its base form). Sammuttavan appears primarily in descriptive, technical, or legal contexts where the relationship between an action and a noun needs to be specified.
