Peräin

Peräin is a Finnish term that can refer to several things, primarily related to boats and vehicles, and also to a specific geographical location. In nautical contexts, peräin refers to the rudder, the steering device used to control the direction of a boat or ship. It is typically a flat piece of wood or metal attached to the stern, and its movement changes the flow of water, thus altering the vessel's course.

The term can also be used more broadly in some technical contexts to describe a rear part or a tail end, though its primary association remains with marine applications. Beyond its mechanical meanings, peräin also designates a village in the municipality of Kemi, located in the Lapland region of Finland. This village, situated in the northern part of the country, carries the name and serves as a local geographical marker. Therefore, understanding the context is crucial when encountering the word peräin, as its meaning can shift between maritime terminology and a specific place name.
