vastapäiseen

Vastapäiseen is an Estonian word that translates to "counterclockwise" in English. It describes a direction of rotation or movement from right to left when viewed from above, following the path of the hands of a clock in reverse. This term is commonly used in everyday language, as well as in more technical contexts such as physics, mathematics, and engineering.

For instance, when describing the turning of a screw, if it tightens when turned in this direction, it is said to be turning vastapäiseen. Similarly, in geometry, the orientation of angles is often measured vastapäiseen from a reference axis. Navigational instructions might also employ the term, indicating a turn in a particular direction. The opposite direction of movement is päripäeva, meaning clockwise. Understanding vastapäiseen is essential for interpreting directions and descriptions of rotational motion in Estonian.
