käytätään

käytätään is the passive past participle of the Finnish verb käyttää, which means "to use". Therefore, käytätään translates to "is used" or "are used" in English. It is a common grammatical form in Finnish, indicating that something is being utilized or employed.

This form is frequently encountered in sentences where the subject is the recipient of the action of using, rather than the performer. For instance, a sentence like "Tämä työkalu käytetään usein rakentamisessa" translates to "This tool is often used in construction." Here, "työkalu" (tool) is the subject, and it is the thing that is being used.

The passive past participle can also be used in more complex sentence structures or to form participial phrases. Its versatility makes it a fundamental element of Finnish grammar for expressing passive voice and describing the state of being used. The context of the sentence will always clarify whether it refers to singular or plural usage.
