rööbast
Rööbast is a term primarily used in Estonian to describe a track or railway. It can refer to the physical structure of a railway line, consisting of rails, sleepers, and ballast, that trains run on. In a broader sense, rööbast can also be used metaphorically to represent a path, course, or direction, whether it be in life, a project, or any other endeavor. For example, one might speak of keeping a project on the right rööbast, meaning to maintain its intended course. The term can also be used to describe a groove or channel, such as a groove in which something slides. The etymology of the word is thought to be related to the concept of "track" or "rut." In some contexts, it can also refer to a pair of parallel lines or grooves. The specific meaning of rööbast often depends on the surrounding words and the context in which it is used.
