paineistettavan

Paineistettavan is a Finnish grammatical form used in technical language. It is the genitive singular of the attributive adjective paineistettava, which is derived from the verb paineistaa and carries the meaning “to be pressurized” or “pressurizable.” The form functions as a modifier in noun phrases, indicating that the noun is intended to be subjected to internal pressure or designed for pressurization.

In practice, paineistettavan is most common in engineering, safety standards, and product specifications. The typical structure is paineistettavan + noun, for example: paineistettavan laitteen tiivisteet (the seals of the device to be pressurized) or paineistettavan säiliön testaus (testing of the container to be pressurized). The form shows a relationship of design or requirement rather than a current action.

Related grammatical forms include paineistettavaa, the partitive singular used with verbs that require a partitive object, as in Tarvitsemme paineistettavaa laitetta (We need a device to be pressurized). The plural genitive would be paineistettavien, as in Paineistettavien laitteiden ohjeet (the manuals of the devices to be pressurized).

Etymology: paineistettava combines paineistaa (“to pressurize”) with the suffix -ttava, producing a present passive participle-like adjective. Paineistettavan thus denotes “the thing to be pressurized” in its genitive singular form.
