Maadoitettuun

Maadoitettuun is a Finnish grammatical form derived from the verb maadoittaa, meaning to ground or earth in electrical terms. The basic sense of maadoitetu* is “grounded,” and maadoitettuun is the illative singular form used to indicate direction toward or into something that has been grounded. In practice, maadoitettuun appears in technical and safety-oriented texts to specify where grounding should be connected or where a grounded state is expected.

In electrical engineering and related disciplines, grounding is a safety and functional measure that connects equipment or conductors to the earth or a conductive reference point. The illative form maadoitettuun is used when describing movement toward or installation into a grounded object or location, for example maadoitettuun koteloon (into a grounded enclosure) or maadoitettuun verkkoon (into a grounded system). The form helps express that the target of grounding has already been established or required.

Etymology and morphology: maadoittaa is the verb “to ground,” maadoitettu is the past participle “grounded,” and maadoitettuun is the illative singular form of that participle. The use is primarily grammatical and stylistic, typical of Finnish technical language, where precise case endings indicate the relationship between elements in a sentence.
