raiteisiin
Raiteisiin is a Finnish term that translates to "onto the tracks" or "onto the rails." It is most commonly used in the context of railways, referring to the act of a train or other rail vehicle moving onto or beginning to travel along a railway track. The phrase implies the transition from a stationary position, such as a station or a siding, to the main line or a designated route. It can also be used metaphorically to describe something that is set in motion or progressing according to a plan. For example, one might say that a project has "gone onto the tracks" to indicate that it has started and is moving forward as intended. The word itself is derived from "raide," meaning track or rail, and the illative case ending "-isiin," which denotes movement into something. Therefore, "raiteisiin" literally signifies entering the space defined by the rails. The concept is fundamental to understanding train operations and can be a useful idiom in everyday Finnish conversation.
